Share. By Anne Marie Helmenstine, Ph.D. Definition: A pi bond is a covalent bond formed between two neighboring atom's unbonded p-orbitals. An unbound p-orbital electron in one atom forms an electron pair with a neighboring atom's unbound, parallel p-orbital electron.This electron pair forms the pi bond.hare.

When an anion and cation connect together, it is called an ionic bond. An ionic bond is a type of chemical bond formed between a cation and an anion. In an ionic bond, one or more electrons are transferred from a cation to an anion.An example of an ionic bond is sodium chloride, abbreviated as NaCl.hen an anion and cation connect together, it is called an ionic bond.
