Answer :
Neon has 8 valence electrons.
Here’s a detailed, step-by-step explanation:
1. Understanding the Concept of Valence Electrons:
Valence electrons are the electrons in the outermost shell of an atom. These electrons determine the chemical properties of the element.
2. Atomic Number of Neon:
The atomic number of Neon (Ne) is 10. This means Neon has 10 protons and, in a neutral atom, also has 10 electrons.
3. Electron Configuration:
Electrons are arranged in shells around the nucleus. The first shell can hold up to 2 electrons, and the second shell can hold up to 8 electrons.
- For Neon, with 10 electrons, the electron configuration is:
- First shell: 2 electrons
- Second shell: 8 electrons
4. Valence Electrons:
The valence electrons are found in the outermost shell of the atom. For Neon, the outermost shell (the second shell) holds 8 electrons.
Therefore, Neon has 8 valence electrons.
