Which part of the atom is responsible for chemical bonding

Answers

It states the fact, which we now know, that electrons are responsible for the chemical bonding. According to this theory, valency is the number of electrons present in the outermost energy shell of the atom. This energy shell is called valency shell.

Final answer:

The electrons located in the valence shell of an atom are responsible for forming chemical bonds by sharing, donating or accepting electrons.

Explanation:

The parts of the atom responsible for chemical bonding are the electrons, which are located in the outermost shell of the atom, also known as the valence shell. These electrons can be shared, donated, or accepted to form chemical bonds with other atoms. For example, in a covalent bond, electrons are shared between atoms. In contrast, in an ionic bond, electrons are transferred from one atom to another, creating ions that are attracted to each other and form a bond.
