Neon has an atomic number of 10 and an atomic mass of approximately 20. How many protons does an atom of neon have?

Explanation / Answer

1. no charge (because the outer shell is already complete)
2. -1 (because it has 7 electrons already and need one more to complete the outer shell)
3. 2 (first shell of any atom contains 2 electrons only)
4. In multiple layers outside the nucleus (these layers are the shells in which electrons revolve around the positively charged nucleus)
5. 4 (atomic number also refers to the number of electrons)
6. 2 (1st shell always contain 2 electrons, in any atom, except H)
7. electrons (present outside nucleus)
8. 197
9. 2
10. 10 (atomic number refers to both electrons and protons)
