Answer: Option (B) is the correct answer.
Explanation:
Chemical bonding is defined as the attractive forces that combining atoms together due to exchange of electrons.
For example, sodium has atomic number 11 and chlorine has atomic number 17.
So, to attain stability sodium loses one electron whereas chlorine gains one electron. This transfer of electrons will result in the formation of an ionic bond.
This bonding that involves exchange of electrons denotes chemical bonding is taking place.
Whereas cations are the species which are formed when an atom loses an electron and anions are the species which are formed when an atom gain electrons.
Valence electrons are the electrons present in the outermost shell of an atom.
Thus, we can conclude that chemical bonding are the attractive force holds one chlorine atom and one sodium atom together to make the substance salt.
