The Atomic Number Of Oxygen Is 8. What Is The Mass Number Of A Oxygen Atom With 7 Neutrons??
The mass number of an oxygen atom with seven neutrons is 15.
What is the atomic mass of oxygen 8?
What is the atomic mass number of an oxygen atomic number 8 isotope that has 10 neutrons?
As “A” is the sum of the number of protons and number of neutrons of an atom therefore “A” for the given oxygen atom is (8+10) or 18. “X” for an oxygen atom is O.
What is the atomic mass number of an oxygen atomic number 8 isotope that has 9 neutrons?
What is the mass number for an oxygen atom that contains 8 neutrons?
Explanation: Since oxygen has 8 protons and 8 neutrons the atomic mass of oxygen is 16 which is the sum of protons and neutrons.
What atom has 8 protons 8 electrons and 9 neutrons?
8 17 This isotope of oxygen has 8 protons (atomic number) 8 electrons and 9 neutrons.
What is the element with 8 electrons?
OXYGEN
So… for the element of OXYGEN you already know that the atomic number tells you the number of electrons. That means there are 8 electrons in an oxygen atom.
How do u calculate atomic mass?
For any given isotope the sum of the numbers of protons and neutrons in the nucleus is called the mass number. This is because each proton and each neutron weigh one atomic mass unit (amu). By adding together the number of protons and neutrons and multiplying by 1 amu you can calculate the mass of the atom.
How do you calculate atomic weight?
The atomic weight of any atom can be found by multiplying the abundance of an isotope of an element by the atomic mass of the element and then adding the results together. This equation can be used with elements with two or more isotopes: Carbon-12: 0.9889 x 12.0000 = 11.8668.
How do you find the atomic number and mass number?
Together the number of protons and the number of neutrons determine an element’s mass number: mass number = protons + neutrons. If you want to calculate how many neutrons an atom has you can simply subtract the number of protons or atomic number from the mass number.

If an oxygen atom has 8 protons and 8 neutrons in the nucleus what is the mass number of oxygen? | 16 |
If an oxygen atom has 8 protons and 8 neutrons in the nucleus what is the atomic number? | 8 |
If an atom has 12 electrons what is its atomic number? | 12 |
What element has 8 proton and 9 neutron?
Answer: The isotope of oxygen has 8 protons (p) 9 neutrons (n) and 8 electrons (e-).
What element has 8 neutrons 7 protons and 10 electrons?
A nitride ion has 7 protons 8 neutrons and 10 electrons.
What is the total charge of 8 protons 8 neutrons and 10 electrons?
Explanation: With eight protons we are necessarily looking at oxygen but with 10 electrons the net charge on the ion is minus two.
What type of element has 8 electrons in their outermost level?
Neon and argon have 8 electrons in their outermost shells. The elements which have 8 electrons in the outermost shell or in the valence shell are known as the noble gases.
What is an element with 8 electrons in its highest main energy level?
A | B |

What type of notation is shown below? | orbital notation |
An element with 8 electrons in its outer shell has a(n) ______ of electrons in its highest energy level. | octet |
Elements with an octet of electrons in their outer shell are called ______ | noble gases |
What element contains 8 protons in its nucleus?
How do you find the atomic mass of oxygen?
It must be experimentally determined using a mass spectrometer. For example since the mass of one atom of oxygen-16 is 1.33291 times the mass of one carbon-12 atom the mass of one oxygen-16 atom should be equal to 1.33291 x 12 = 15.99492 atomic mass units.
What is called atomic mass?
An atomic mass (symbol: ma) is the mass of a single atom of a chemical element. It includes the masses of the 3 subatomic particles that make up an atom: protons neutrons and electrons. Atomic mass can be expressed in grams. … 1 atomic mass unit is defined as 1/12 of the mass of a single carbon-12 atom.
How do you find atomic number?
The symbol for an atom can be written to show its mass number at the top and its atomic number at the bottom. To calculate the numbers of subatomic particles in an atom use its atomic number and mass number: number of protons = atomic number. number of electrons = atomic number.
What is an atomic number and atomic mass?
Is atomic mass and mass number the same?
What is atomic mass Class 9 CBSE?
Atomic mass refers to the mass of an atom. It depicts how many times an atom of an element is heavier than one-twelth (1/12th) the mass of one atom of carbon-12 of mass of one carbon atom. … It is measured in unit called amu (atomic mass unit). 1/12 of the mass of one atom of carbon is termed as relative atomic mass.
What is atom in science class 8?
An atom is defined as the structural and functional unit of a matter. The term “atom” comes from the Greek word which means indivisible because atoms are the smallest things in the universe and could not be divided. atoms are made up of three subatomic particles like protons neutrons and electrons.
How do you calculate atomic mass example?
