Question

What is a bond

Answer 1

In chemistry, a bond or chemical bond is a link between atoms in molecules or compounds and between ions and molecules in crystals. A bond represents a lasting attraction between different atoms, molecules or ions.

Why Bonds Form
Most of bonding behavior can be explained by the attraction between two opposite electrical charge. The electrons of an atom or ion are attracted to their own positively-charged nucleus (containing protons), yet also to the nuclei of nearby atoms.Species that participate in chemical bonds are more stable when the bond is formed, typically because they had an imbalance of charge (greater or fewer number of electrons than protons) or because their valence electrons did not fill or half-fill electron orbitals.
