Detailed explanation-1: -A chemical bond is a force of attraction between atoms or ions. Bonds form when atoms share or transfer valence electrons. Valence electrons are the electrons in the outer energy level of an atom that may be involved in chemical interactions.

Detailed explanation-2: -A covalent bond indicates the sharing of electrons between atoms. Compounds that contain carbon (also called organic compounds) commonly exhibit this type of chemical bonding. The pair of electrons which are shared by the two atoms now extend around the nuclei of atoms, leading to the creation of a molecule.

Detailed explanation-3: -Chemical bond refers to the forces holding atoms together to form molecules and solids. This force is of an electric nature, and the attraction between electrons of one atom to the nucleus of another atom contributes to what is known as chemical bonds.

Detailed explanation-4: -15. The reason a bond is formed between chloride ions and sodium ions is because they have opposite charges. TRUE: the opposite charges attract them together, and this force of attraction is the ionic bond.
