Atomic number Z represents the number of protons per atom. Mass number Z + N is equal to the number of protons Z plus the number of neutrons N present in the nuclei. Mass numbers of the most abundant isotopes are given in order of decreasing abundance. For example, Cadmium Cd-48 mass ...
Do remember that the atomic number is the number of protons (or positive charges) in a nucleus. It was a discovery made by Henry G J Moseley. Moseley found that certain lines in the X-ray spectrum moved each time he was using a new element. He rearranged the different ...
the difference is the number of protons found in the nucleus of the atoms. the number of protons makes each element unique, so they are organized by these numbers on the periodic table. the number of protons that are found in an atom of an element is called the atomic number. on the ...
The mass number of lithium is 7. The mass number of any element is equal to its number of protons and neutrons. You can figure out the number of... Learn more about this topic: Atomic & Mass Number | Overview & Difference from
of the element's name is the mass number. The mass number represents the number of protons plus neutrons in the nucleus of an atom of the element. The number of protons determines the element, but the number of neutrons in the atom of any one element can vary. Each variation is an ...
