Atomic Mass is the mass according to the number of protons and neutrons in the nucleus of the atom. The actual mass is the average of the masses of the different isotopes of the same element (alternative forms of the same element with the same no of protons but different no of neutrons) accordong to the isotopes mass and abundance in the world.

What is hydrogen's atomic mass number?
Hydrogen is a gas. Mass number of it is 2.
What is the atomic mass 20 gas?
The atomic mass of an element is the average mass of an atom of that element. For a gas with an atomic mass of 20, it could be calcium (Ca). Calcium has an atomic number of 20 and an atomic mass of approximately 40.08 grams per mole.
What is the relative mass formula of hydrogen gas?
The molecular mass of hydrogen gas is 2. A molecule of hydrogen gas contains two hydrogen atoms covalently bonded. Since each hydrogen atom has an atomic mass of 1 (as we can derive from the Periodic Table of Elements), the molecular mass of hydrogen gas as a molecule is 1 + 1 = 2.
What element Nobel gas with atomic mass of 226?
Radon has atomic mass of 222. There is isotope of Radon with mass number 226. Radon is a Nobel gas.
What is the atomic mass number for nitrogen?

What is chlorine gases number of atomic mass?
Chlorine gas is Cl2. Cl's atomic mass is 35.45 and that x 2 is 70.9
Gas atomic mass 16 8 nuetrons?
The number of protons and neutrons in an atom is equal to its atomic mass. Since the atomic mass of this gas atom is 16 and it has 8 neutrons, the remaining mass (16-8=8) must be the protons in the nucleus. Therefore, this gas atom has 8 protons.
What is the atomic number of the Nitrogen?
The atomic number of nitrogen (N) is 7. The atomic weight of N is 14.00674 grams per mole. Nitrogen gas exists as a diatomic molecule: N2.
What element is a gas with mass number of19?
Fluorine is a non metal element. Atomic mass number of it is 19.
What is molecular mass of pure gas?
The molecular mass of a pure gas is the sum of the atomic masses of all the atoms in its molecule. It is typically measured in atomic mass units (amu) or grams per mole (g/mol). The molecular mass is useful for calculating other properties of the gas, such as density or molar volume.
Is hydrogens atomic number 1.008?
Hydrogen is a gas element. atomic number of it is 1.
What is the name of the gas that has atomic mass 16 and 8 neutrons?
That would be oxygen (16O).
