Answer 2

1. A covalent bond is formed between two atoms by sharing of an electron pair.

2. This type of bond is usually formed between two non-metal atoms.

3. A covalent bond has directional nature. This gives definite shape to a covalent molecule. For example, the methane molecule, CH4, has regular tetrahedral shape, and the ammonia molecule, NH3, has pyramidal shape, with definite bond angles.

4. When a covalent bond is formed between atoms of different elements with different electronegativity values , the bond tends to have certain amount of polar or ionic characteristic. For example, the covalent HCl molecule seems to have partial ionic character due to the difference in electronegativity between the hydrogen and chlorine atoms.
