losing, gaining or sharing of electrons.
Statement-2 : Hydrogen forms electrovalent and covalent
bonds with other elements.

Answer 1

Answer:

Both statement 1 ans statement 2 are correct

Answer 2

Question - Statement-1 : Hydrogen combines with other elements by

losing, gaining or sharing of electrons.

Statement-2 : Hydrogen forms electrovalent and covalent

bonds with other elements.

( A ) Statement – 1 is true, Statement – 2 is true; Statement -2 is not a correct explanation for Statement-1.

( B ) Statement – 1 is true, Statement – 2 is False

( C ) Statement – 1 is false, Statement – 2 is true

( D ) Statement – 1 is true, Statement – 2 is true; Statement -2 is correct explanation for Statement-1.

Answer - correct option with respect to hydrogen is- ( A ) Statement – 1 is true, Statement – 2 is true; Statement -2 is not a correct explanation for Statement-1.

Ionic bonds is also known as electrovalent bond. It is formed by gaining or losing electrons.

Hydrogen can gain electron as in sodium hydride or NaH formation. Reaction is -

Na+ + H- --> NaH.

Hydrogen can lose electron as in formation of hydrochloric acid or HCl. Reaction is -

H+ + Cl- --> HCl.

Covalent interactions occur by sharing of electrons, as in methane or CH4. In methane, carbon has four electrons and hydrogen has one electron.

Hydrogen and carbon share electrons to complete eight electrons for carbon and two electrons for hydrogen.
