Average Atomic Mass (Mass # = Protons + Neutrons)

Atomic Number: The number of protons in every atom of an element(Can also represent the number of electrons in a neutral atom.)

Electron Configuration:The number of electrons in each energy level; add the numbers to get the total number of electrons.

Element Symbol: The letter(s) used to identify an element

Oxidation Numbers: Possible charges an atom of an element can have

Example: Chlorine has two isotopes which have an average atomic mass of

35.453 amu: Cl-35 and Cl-37

Sep 17­8:30 PM

Calculating Average Atomic MassTry it:

Naturally occurring chlorine that is put in pools is 75.53% 35Cl (mass = 34.969 amu) and 24.47% 37Cl (mass = 36.966 amu).

Calculate the average atomic mass.
