The same number as the atomic number which can be found on top of the element on the periodic table.

Question 14

To get the number of electrons look to see if the element is neural, a cation, or an anion.

Answer 14

Ex: 2-
If your anion’s proton count is 8, that means your electron count will be 10 because 10-2 =8
