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.
The ______________________ of an element is the average mass of an element’s naturally occurring atom, or isotopes, taking into account the ____________________ of each isotope.
The _______________________ of an element is the total number of protons and neutrons in the ___________________ of the atom.
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 ______________________.
