Answer 1

1. If combining atoms of a compound have nearly similar electronegativities the bond between them is covalent.

2. Elements with low electronegativity are usually metallic

3. An atom is said to be a non-metal, if it gains one or more electrons.

4. Atoms with small atomic radii and high ionisation potential tend to gain electrons.

5. Element ‘X’ in period 3 has high electron affinity and electronegativity. It is likely to be a non-metal.
