Neon has 8 valence electrons. Neon is a noble gas, and it is located in Group 18 of the periodic table. Elements in this group have a full outer shell of electrons, which makes them very stable and unreactive.
Here’s a brief explanation:
- Neon’s atomic number is 10, which means it has 10 electrons in total.
- These electrons are arranged in two shells: the first shell has 2 electrons, and the second shell has 8 electrons.
- The outermost shell, which is the second shell in this case, contains the valence electrons. Since the second shell is fully occupied with 8 electrons, neon has 8 valence electrons.
This full outer shell is the reason why neon is chemically inert and does not easily form compounds with other elements.
