🗑
the____ is the number of protons in the nucleus of an element's atoms   atomic number  
🗑
Explain why a neutral atom must have the same number of protons and electrons?   A neutral atom must have the same amount of protons and electrons so they cancel each other out, leaving it with no charge.  
🗑


   

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
