1. The number of protons in one atom of an element determines the atom’s _________________, and the

number of electrons determines the _________________________ of the element.

2. The atomic number tells you the number of ___________________________ in one atom of an element.

It also tells you the number of __________________________ in a neutral atom of that element. The

atomic number gives the “identity” of an element as well as its location on the periodic table. No two

different elements will have the ____________________ atomic number.

3. The ______________________ of an element is the average mass of an element’s naturally occurring

atom, or isotopes, taking into account the ____________________ of each isotope.

4. The _______________________ of an element is the total number of protons and neutrons in the

___________________ of the atom.

5. The atomic mass is used to calculate the number of ______________________ in one atom of an

element. In order to calculate the number of neutrons you must subtract the ______________________

from the ______________________.
