When 1 carbon atom combines with two oxygen atoms What is the resulting substance?
This group of atoms is the smallest combination of atoms that retains the properties of a substance called carbon dioxide. It is made of 1 carbon atom and 2 oxygen atoms.
Carbon dioxide: It is a colorless and odorless molecule. Conposed of one carbon atom and two oxygen atom. It can be produced in various ways for example combustion. Carbon Dioxide: CO2 : chemical compound composed of two oxygen atoms covalently bonded to a single carbon atom.

When two or more atoms combine the resulting object is called a n?
Chemical Reactions and Molecules
When two or more atoms chemically bond with each other the resultant chemical structure is a molecule.
What does 2 oxygen atoms make?
Two oxygen atoms strongly bind together with a covalent double bond to form dioxygen or O2. Oxygen is normally found as a molecule. It is called dioxygen.
What is the number at the end of an isotope’s name?
Answer Expert Verified The number of protons and electrons remain same for two isotopes. This means isotopes have different mass number but have same atomic number. When we write an isotope the number at the end of the isotope’s name is the mass number.
When oxygen combines with an element to form a compound the resulting compound is called?
The reaction between oxygen and another element generally results in the formation of a binary compound known as an oxide.
What is produced when two atoms combined?
Atoms of different elements can combine to make new substances. A molecule is formed when two or more atoms join together chemically. If atoms combine that are of two or more different elements we call that a compound. All compounds are molecules but not all molecules are compounds.
What happens when carbon combines hydrogen?
They are always shared in pairs so a covalent bond may consist of two four or six electrons being shared. … For example carbon and hydrogen atoms share electrons to form covalent bonds in methane CH4. Rules about combining power are still obeyed when carbon and hydrogen atoms combine to form ethane C2H6.
What is hydrogens number?
Hydrogen is a chemical element with symbol H and atomic number 1. Classified as a nonmetal Hydrogen is a gas at room temperature.
What is it called when atoms join together?
When atoms join together the group is called a molecule. The atoms in a molecule can the the same. For example nitrogen gas molecules are just two…
When two or more atoms ions or molecules combine to form a new and larger molecule?
Atoms can combine into ionic lattice structures or into covalent molecules. When different types of atoms combine the result is called a compound.
When two oxygen atoms come together they form a N?
Non Polar covalent bond is formed when oxygen atoms bond together in. Explanation: A covalent bond is formed when an element shares its valence electron with another element. This bond is formed between two non metals.
Why is oxygen called O2?
The difference between oxygen (O) and oxygen (O2 )is that the former is an oxygen atom while the latter consists of two O atoms bound together forming a molecule also called oxygen. Oxygen is usually found as a diatomic gas. Therefore we write it as O2.
What is the atomic number of N?
What is the number at the end of an isotope’s name atomic number neutron number?
– The liquid contains only one element. -The liquid is a pure substance. The number at the end of an isotope’s name is the -mass number. While looking at xenon (Xe) on the periodic table a student needs to find an element with a smaller atomic mass in the same group.
What are the two parts of an atom?
An atom is composed of two regions: the nucleus which is in the center of the atom and contains protons and neutrons and the outer region of the atom which holds its electrons in orbit around the nucleus.

How is the name of each element in the periodic table represented?
In the typical periodic table each element is listed by its element symbol and atomic number. For example “H” denotes hydrogen “Li” denotes lithium and so on. Most elements are represented by the first letter or first two letters of their English name but there are some exceptions.
What happens when the elements in Group 1 react with oxygen?
The group 1 elements react with oxygen from the air to make metal oxides . … This forms a white oxide which covers the surface. The metal below the surface does not react. The alkali metals burn vigorously when heated and placed in a gas jar of oxygen.
What happens when the elements in group 2 react with oxygen?
All Group 2 elements tarnish in air to form a coating of the metal oxide. They react violently in pure oxygen producing a white ionic oxide. … This reaction is a redox reaction where the metal loses electrons to form a positive ion – oxidation. The oxygen gains electrons to form a negative ion – reduction.
What elements does oxygen combine with?
Oxygen is reactive and will form oxides with all other elements except the noble gases helium neon argon and krypton.
What is produced when two atoms combine?
When atoms combine through chemical bonding they form compounds—unique structures composed of two or more atoms.
What will be produced if carbon atom is combined chemically with oxygen atom?
An atom of Carbon will combine with two atoms of Oxygen to form carbon dioxide (CO2) or two atoms of Hydrogen will combine with one atom of Oxygen to form water (H20).
What is carbon hydrogen and oxygen?
Carbohydrates are organic compounds that contain only carbon hydrogen and oxygen. They are the most common of the four major types of organic compounds. There are thousands of different carbohydrates but they all consist of one or more smaller units called monosaccharides.
When carbon and hydrogen are combined with oxygen they * 1?
Explanation: when carbon and hydrogen are component with oxygen they can cause fire.
When carbon and hydrogen are combined with oxygen there?
When the carbon is reacted with hydrogen the oxygen is liberated as water and the ratio of methane molecules produced to oxygen atoms removed is found to be of the order 1 : 2 this provides additional evidence for the above observation.
What is n on the periodic table?
Nitrogen – Element information properties and uses | Periodic Table.
What does H2 stand for in chemistry?
H2 means two hydrogen atoms. O2 means two oxygen atoms. The number before the element is the number of molecules. 2H2 means two molecules of hydrogen and four hydrogen atoms.
What is a H2 molecule?
Molecular hydrogen gas or H2 is the primary form in which hydrogen is found. In other words two hydrogen atoms (H) are covalently bonded (a type of chemical bond) together as H-H. … Because the hydrogen atoms are covalently bonded together they form a molecule so H2 is also referred to as molecular hydrogen.
When one oxygen atom shares two pairs of electrons with another oxygen atom o2 How is formed?
Two covalent bonds
Two covalent bonds form between the two oxygen atoms because oxygen requires two shared electrons to fill its outermost shell.
See alsowhy do earthquakes occur only above the brittle/plastic transition depth?
What do molecules combine when combined?
Two or more atoms combine to make molecules and these molecules combine to make compound.
When two or more atoms join together by sharing their outermost electrons?
covalent bond: An interaction between two atoms which involves the sharing of one or more electrons to help each atom satisfy the octet rule.
When two oxygen atoms are covalently bonded together we have?
When two oxygen atoms bond together to form an oxygen molecule they share four electrons ? two from each oxygen atom. Other examples of covalent bonding are water (H2O) and carbon dioxide (CO2). Covalent compounds are usually liquids or gases with low melting points.
Why is n2 a triple bond?
Nitrogen has five valence electrons so it needs three more valence electrons to complete its octet. A nitrogen atom can fill its octet by sharing three electrons with another nitrogen atom forming three covalent bonds a so-called triple bond. … In fact the triple bond in nitrogen is one of the strongest bonds known.
How are monomers connected?
The monomers combine with each other via covalent bonds to form larger molecules known as polymers. … The removal of a hydrogen from one monomer and the removal of a hydroxyl group from the other monomer allows the monomers to share electrons and form a covalent bond.
Carbon and oxygen are known to form two compounds. The carbon content in one of these is 42.9% .
