Write the Lewis dot symbols and predict the valencies you expect for the following elements :
Nitrogen , Fluorine and Neon

Explanation

To solve the problem of writing the Lewis dot symbols and predicting the valencies for nitrogen, fluorine, and neon, we will follow these steps:

### Step 1: Determine the Atomic Number and Electronic Configuration
- **Nitrogen (N)**: The atomic number is 7. The electronic configuration is 1s² 2s² 2p³, which gives us a total of 5 valence electrons (2 in the 2s subshell and 3 in the 2p subshell).
- **Fluorine (F)**: The atomic number is 9. The electronic configuration is 1s² 2s² 2p⁵, resulting in 7 valence electrons (2 in the 2s subshell and 5 in the 2p subshell).
- **Neon (Ne)**: The atomic number is 10. The electronic configuration is 1s² 2s² 2p⁶, which means it has 8 valence electrons (2 in the 2s subshell and 6 in the 2p subshell).
