Example 20–Distribution of Isotopes Between Water and Calciteiso.dat
The number of protons determines the element of the atom, while the number of neutrons can vary (resulting in different isotopes of the same element). Electrons exist in energy levels or shells around the nucleus, and each shell can hold a specific number of electrons. Example of an atom: ...

Atomic mass is the average mass of all of the isotopes of a particular element. It's a weighted average that takes into consideration the percent abundance of each naturally occurring isotope of any particular element. The unit that is often associated with atomic mass is called an atomic mass...
