What Determines The Chemical Properties Of An Atom??
A neutral atom has an equal number of protons and electrons so that the positive and negative charges exactly balance. Since it is the electrons that determine how one atom interacts with another in the end it is the number of protons in the nucleus that determines the chemical properties of an atom.
What determines the chemical properties of an atom quizlet?
The chemical properties of an element are determined by the number of protons in the nucleus. This number of protons is called the atomic number. The mass of the atom its atomic mass depends upon the sum of the number of protons and the number of neutrons present in the nucleus.
Which of the following most determines the chemical properties of an atom?
What determines the chemical and physical properties of an atom?
Chemical properties of each element are determined by the element’s electronic configuration and particularly by its outermost valence electrons. … In addition the total number of electron shells an atom determines which period it belongs to.
What determines the chemical and physical properties of an atom of an element?
Electrons located in the outermost shell of the electron cloud are called “valence electrons” and have the highest energy. Valence electrons determine the chemical properties of an element or how the valence electrons of one element are shared or traded with valence electrons of other elements to create new molecules.
Which part of the atom determines the atom?
What determines the chemical identity of an atom or ion?
The identity of an atom is determined by its proton number or atomic number. For example any atom having 6 protons is classed as carbon. Atoms are neutral entities so they always have equal numbers of positively charged protons and negatively charged electrons.
Which of the following determines chemical properties?
The chemical properties of an element are determined by the number of protons in the nucleus. … The mass of the atom its atomic mass depends upon the sum of the number of protons and the number of neutrons present in the nucleus.
What subatomic particle determines the atom?
How an atom behaves is determined by its?
The chemical behavior of atoms is determined by the number and the configuration of the electrons in the atom. … The number of protons in the nucleus determines the number of electrons in the atom. More on Atoms. Most atoms in the world around us are electrically neutral.
What determines the identity of a substance?
Typically the identity of a substance can be described by a: chemical name for example benzene … chemical composition for example >99 % benzene and <1 % toluene. The composition is determined by chemical analysis.
What determines the identity of a chemical element?
The atomic number is the number of protons in the nucleus of an atom. The number of protons define the identity of an element (i.e. an element with 6 protons is a carbon atom no matter how many neutrons may be present).
Do atoms of the same element have the same chemical properties?
All atoms of the same element have the same number of protons but some may have different numbers of neutrons. … Different isotopes of an element generally have the same physical and chemical properties because they have the same numbers of protons and electrons.
Which of the following determines the atomic number of an atom?
What are the 4 properties of the atom?
Atoms. Atoms are the smallest fraction of an element that can exist and still show the characteristics of the element. Atoms themselves are composed essentially of electrons (1 negative charge) protons (1 positive charge) and neutrons (no charge).
What determines the types of chemical reactions that an atom participates in?
| An example of a stimulus that a plant would respond to is: | Plants can respond only to certain stimuli in the environment such as sunlight |
|---|---|
| What determines the types of chemical reactions that an atom participates in? | the number of electrons in the outermost electron shell |
Which subatomic particle determines the chemical properties of an element?
What particle or particle determines what element an atom is?
The number of protons in the nucleus determines which element an atom is while the number of electrons surrounding the nucleus determines which kind of reactions the atom will undergo. The three types of subatomic particles are illustrated below for an atom of helium—which by definition contains two protons.
What is the one thing that determines the identity of an atom that is whether it is an oxygen atom or a carbon atom etc?
How are the atomic number and the number of protons related to each other? How do the number of protons number of neutrons and the mass number relate to each other? What is the one thing that determines the identity of an atom (that is whether it is an oxygen atom or a carbon atom etc.)?
What factors determine the physical properties of a substance?
- The kinetic energies of the particles (atoms molecules or ions) that make up a substance. Kinetic energy tends to keep the particles moving apart.
- The attractive intermolecular forces between particles that tend to draw the particles together.
How do you determine the physical properties of a substance?
Physical properties are those general properties you notice most readily about a substance such as its size state of matter (solid liquid or gas) color mass density and strength. Values for physical properties can be determined by tests that don’t alter the substance being tested.
What determines the identity of an atom quizlet?
The identity of the atom is determined by the number of protons an atom with five protons has different properties than an atom with six protons. … We use a very small unit of mass to measure them and this unit is called an atomic mass unit (amu).
Do electrons determine the identity of an atom?
Since electrons can be lost or gained or shared electrons cannot determine an atom’s identity. Only the number of protons of an element do not change.
What makes one atom different from another?
The number of protons in an atom is the defining feature of an atom. It’s what makes one element different from another. The number of protons in an atom is called its atomic number. … All the elements in the universe are arranged according to their atomic number in the periodic table.
How are atoms of the same element similar and different?
ISOTOPES AND ATOMIC MASSES
For many of the chemical elements there are several known isotopes. Isotopes are atoms with different atomic masses which have the same atomic number. The atoms of different isotopes are atoms of the same chemical element they differ in the number of neutrons in the nucleus.
How can atoms of the same element have different properties?
Two atoms of the same element can be different if their electrons are in different states. If one copper atom has an electron in an excited state and another copper atom has all of its electrons in the ground state then the two atoms are different.
Is an atom a chemical?

What is property of an atom?
The parts of an atom have electrical charges. Each proton carries a positive electrical charge and each electron has a negative electrical charge. Neutrons have no charge. In most cases an atom has the same number of protons and electrons. It is electrically neutral.
What are properties in atoms?
Physical properties of matter include hardness malleability color and melting point. The important point here is that chemical and physical properties of matter depend only on the electron cloud surrounding the atoms. Therefore they depend only on the number of protons in the nucleus.
Is the number of protons in the nucleus of an atom which determines the chemical properties of an element and its place in the periodic table?
What must be the same if two atoms represent the same element?
Two atoms always represent the same element if they have … the same number of protons. The number of protons defines a chemical element. … Isotopes have the same number of protons different numbers of neutrons.
What is the tendency of molecules of the same kind to stick together?
Answer: The tendency of similar particles to stick to each other is called cohesion. … Cohesion is the property of like molecules – molecules of the same substance – to stick to each other due to mutual attraction. Adhesion is the property of different molecules or surfaces to cling to each other.
Which particle determines the chemical properties of a substance?
Explanation: The chemical properties of an element are determined by the subatomic particle known as a proton.
Which subatomic particle of the three determines how an atom behaves when it comes into contact with another atom?
The distribution of electrons determines an atom’s chemical properties and how they will react with other atoms.
