What happens when two atoms form a chemical bond?A) Two atoms fuse together to form a chemical bondB) The atoms share or transfer electronsC) A chemical bond forms when two atoms transfer or share protons to achieve a stable nucleusD) Like charges in the atoms cause them to stick together

A chemical bond is formed when there is a transfer or sharing of electrons. When there is a transfer, what we have is that the electrons completely leave the outermost shell of an atom, usually metal to the outermost shell of another atom, usually a nonmetal. This particularly alters the electronic configuration of these atoms. This is ionic or electrovalent bonding

Now, electron sharing is also another way of chemical bond formation. Electrons might be shared between two atoms in a case principally known as covalent bonding. The electrons here are controlled by the 2 nuclei
