Atomic Structure
1. All atoms are made up of small particles called .
2. These small particles include the positively charged , the negatively charged and the neutral .
3. The atomic mass equals the and the .
4. The atomic number tells you the number of which is equal to the number of in a stable atom.
5. So, we can use the atomic mass and the atomic number to calculate the total number of just the neutrons. Calculate the number of neutrons in a Carbon atom.
