Question

How many valence electrons does carbon have

Answer 1

Carbon has 4 valence electrons, oxygen has 6

Answer 2

Answer:

Carbon has 4 valence electrons

Explanation:

The valence electrons are those found in the last energy level of the atom.

They are responsible for the interaction between atoms,

they can form bonds.

Let's see the electronic configuration of carbon.

The atomic number of C is 6 (Z=6)

$C= 1S^2 2S^2 2P^2$

To know the number of valence electrons that we have we count in the last energy level of the atom.

The last energy level of carbon is 2 and we 4 electrons is this level.

So carbon has 4 valence electrons.
