Question

Discuss the formation of
i) Na-Cl ii) H2O iii) Cl-Cl​

Answer 1

$\huge{\mathtt{\underline{\underline{\red{Answer}}}}}$

1.) Na-Cl:

Sodium and chlorine contain one and seven electrons, respectively, in their outermost shells. Hence, sodium transfers its one electron to chlorine atom and their octets get stabilised. In a sodium chloride molecule, sodium atom transfers its one electron to chlorine atom to form an ionic bond.

2.) H2O:

When the chemical reaction is complete, all that remains is a collection of water molecules, each of which contains one oxygen atom and two hydrogen atoms. ... In the case of water, each molecule contains one oxygen and two hydrogen atoms, and so the formula is H2O.

3.) Cl-Cl:

It is formed when the element chlorine (a halogen) gains an electron or when a compound such as hydrogen chloride is dissolved in water or other polar solvents.
