![Page 1: Atomic Mass. Atomic Number (A) Number of protons in the nucleus Atoms of the same element all have the same number of protons In a neutral atom, the total.](https://reader036.fdocuments.us/reader036/viewer/2022082322/56649f305503460f94c4b7d8/html5/thumbnails/1.jpg)
Atomic Mass
![Page 2: Atomic Mass. Atomic Number (A) Number of protons in the nucleus Atoms of the same element all have the same number of protons In a neutral atom, the total.](https://reader036.fdocuments.us/reader036/viewer/2022082322/56649f305503460f94c4b7d8/html5/thumbnails/2.jpg)
Atomic Number (A) Number of protons in the nucleus Atoms of the same element all have the
same number of protons In a neutral atom, the total number of
protons is equal to the total number of electrons

Mass Number (Z) Total number of protons and neutrons in
nucleus Electrons are so small, there mass is
insignificant to the atomic mass

Example How many protons, neutrons, and electrons
in
1) 3H
2) 235U
3) carbon-12
4) magnessium
5) 41Ca2+
6) 81Br -

Isotopes Atomic masses can be different for atoms
of the same element if they have different numbers of neutrons
Atoms with different masses are called Isotopes or Nuclides
