How many valence electrons are in C2?

Answer 1

C is 4*2

H is 1*2

For a total of 10 valence electrons

Answer 2

A carbon atom has 4 valence electrons. I am not sure what you mean by C2; do you mean two carbon atoms? If so, they have 8 valence electrons between them.

Answer 3

valence of C2H4 is 12 but usually it is 2+ charge so in that case it will be 10

Answer 4

There are 12 valence electrons in a C2 molecule. Each carbon atom contributes 4 valence electrons, and since there are 2 carbon atoms in C2, the total is 8.

Answer 5

it has 10 valence electrons
