Question

Why can a hydrogen atom form a covalent bond without fulfilling the octet rule?

Answer 1

Answer;

Hydrogen's valence shell can hold only up to two electrons.

Explanation;

• Covalent bonds are types of bonds that are formed between non-metals as a result of sharing electrons between atoms. Atoms will covalently bond with other atoms in order to gain more stability, which is gained by forming a full electron shell.
• By sharing their outer most electrons, atoms can fill up their outer electron shell and gain stability.
• According to octet rule, When atoms react, they tend to achieve an outer shell having eight electrons. This is not the case for hydrogen as it obtains a stable valence shell configuration by sharing a single pair of electrons with another atom.
