1. Atomic Number: Neon (Ne) has an atomic number of 10. This means it has 10 protons and 10 electrons in a neutral atom.
2. Electron Configuration: The electron configuration of neon is 2, 8. This means:
* First Shell (n=1): 2 electrons
* Second Shell (n=2): 8 electrons
3. Third Shell: Neon does not have a third shell. Its electrons fill up completely in the first two shells.
Therefore:
* First shell: 2 electrons
* Second shell: 8 electrons
* Third shell: 0 electrons
