How is a chemical bond created?

Answer 1

When an atom that has an excess electron - that it needs to get rid of to be Happy - meets an atom that needs to accept an electron - to be Happy- , they readily share these two electrons in a paired configuration that is called the covalent bond.

Answer 2

A chemical bond is created when atoms share or transfer electrons to achieve a stable state. This can occur through the sharing of electron pairs (covalent bond) or the transfer of electrons resulting in attraction between oppositely charged ions (ionic bond). The type of bond formed depends on the electronegativity and reactivity of the atoms involved.
