Question 1

How many valence electrons does carbon have?

Accepted Answer

carbon has four valence electrons. That is, there are 4 electrons present in the last cell of carbon.

Question 2

How many valence electrons does oxygen have?

Accepted Answer

The valence electron of oxygen will be 6. Because when you look at the electronic configuration of oxygen, there are 6 electrons present in the last cell(valence cell).

Question 3

How many valence electrons do Fluorine have?

Accepted Answer

The valence electron of fluorine is 7. That is, fluorine will gain 1 electron and gain the electronic configuration of neon. And the valency of fluorine will be 1.

Question 4

How many valence electrons does Nitrogen have?

Accepted Answer

There are five electrons present in the last cell of nitrogen. Thus, the valence electron of nitrogen will be five.

Question 5

What is Valancy of Carbon

Accepted Answer

According to the octet theory, in order for each element to reach a stable state, the number of electrons it leaves, or gain or mutual shares in order to fill its octet, we will call that element the valence. Thus, the valency of carbon is four.
