20.1797 is its atomic mass
The number of protons in an atom's nucleus is its atomic number. Each element has its own unique atomic number. An individual atom's atomic mass is the sum of the masses of the protons, neutrons, and electrons in the atom.
Mercury is a non metal element. Atomic mass of it is 200.59.
The atomic mass of Lithium(Li) is 6.941g.
The atomic mass of neon is 20.1797 amu
K, or potassium, has a mass number of 19. Fluorine is a non metal element. Mass number of it is 19. No, mass number for potassium is not 19. That is the atomic number.
The atomic mass is the can be determined by the number of protons in an atom. Remember that a proton has an atomic mas number of 1 AMU (atomic mass unit). (The total mass of an atom is the protons, neutrons and electrons combined.)
Neon
If two atoms have the same atomic number, it means they have the same number of protons in their nucleus. If they also have the same atomic mass, it means they have an equal number of protons and neutrons. These atoms would be isotopes of the same element.
