GENERAL KNOWLEDGE

Detailed explanation-1: -Why form chemical bonds? The basic answer is that atoms are trying to reach the most stable (lowest-energy) state that they can. Many atoms become stable when their valence shell is filled with electrons or when they satisfy the octet rule (by having eight valence electrons).

Detailed explanation-2: -To achieve greater stability, atoms will tend to completely fill their outer shells and will bond with other elements to accomplish this goal by sharing electrons, accepting electrons from another atom, or donating electrons to another atom.

Detailed explanation-3: -Atoms form chemical bonds to achieve a full outer energy level, which is the most stable arrangement of electrons. There are three different types of chemical bonds: covalent, ionic, and metallic bonds.

Detailed explanation-4: -The electrons in the outermost shell of atoms are those that become involved in chemical bonds. These are called valence electrons.

Detailed explanation-5: -The electrons on the outermost energy level of the atom are called valence electrons. The valence electrons are involved in bonding one atom to another. The attraction of each atom’s nucleus for the valence electrons of the other atom pulls the atoms together.
