Answer 1

2) Both are true but Reason is not the correct explanation for Assertion.

• The compounds are formed to become stable with each other and are formed by sharing/gaining/losing electrons.
• The ionic bonds are formed when the electrons are gained or lost whereas covalent bonds are formed when electrons are shared.
• When two similar kinds of atoms are bonded, then it forms an element whereas when two or more different kinds of atoms are bonded, it forms a compound.
