Answer:
8
Step-by-step explanation:
Methyl anion (CH₃⁻)
Valence electrons of carbon = 4
Valence electrons of hydrogen = 1
Charge = -1 which means addition of 1 electron
The total number of the valence electrons = 4 + 3(1) + 1 = 8
In the Lewis structure of anion also, 1 lone pair and 3 bond pairs on the carbon atom which corresponds to 8 valence electrons.
