Question
a carbon atom is able to form four single covalent bonds because it
a) has four electrons and four protons.
b) has four valence electrons in its outermost energy level.
c) forms a polyatomic ion with a -4 charge.
d) forms a more stable isotope when it gains four more electrons.

Answer : The correct option is, (B) has four valence electrons in its outermost energy level.

Explanation :

As we know that the carbon is a non-metal that belongs to group 14 and period 2.

The atomic mass of carbon = 12

The atomic number of carbon = 6

The number of electrons in carbon = Atomic number = 6

The electronic configuration of carbon is,

From the electronic configuration we conclude that there are four number of valence electrons present in outermost energy level of carbon atom that means carbon atom has ability to form four single covalent bonds to another atom.

Hence, the correct option is, (B)
