Which part of the atom is involved in bonding? a. all electrons b. or c. protons d. valence electrons

Hola there!

Answer is valance electrons

➡️A chemical bond is defined as an attractive force that holds the constituents (atoms, ions etc.) together in a chemical species.✔️

➡️Various theories have been suggested for the formation of chemical bonds such as the electronic theory, valence shell electron pair repulsion theory, valence bond theory, and molecular orbital theory.✔️

➡️A chemical bond formation is attributed to the tendency of a system to attain stability. ✔️

➡️It was observed that the inertness of noble gases was because of their fully filled outermost orbitals.✔️

➡️Hence, it was postulated that the elements having incomplete outermost shells are unstable (reactive). ✔️

➡️Atoms, therefore, combine with each other and complete their respective octets or duplets to attain the stable configuration of the nearest noble gases. ✔️

➡️This combination can occur either by sharing of electrons or by transferring one or more electrons from one atom to another.✔️

➡️The chemical bond formed as a result of sharing of electrons between atoms is called a covalent bond. ✔️

➡️An ionic bond is formed as a result of the transference of electrons from one atom to another.✔️

The answer would be a. aluminum can
