Chemical Bonds

A chemical bond is a lasting attraction between atoms that enables the formation of chemical compounds.

The two main types of chemical bonds are ionic bonds and covalent bonds.

An ionic bond is a type of chemical bond formed through the transfer of electrons from one atom to another, resulting in the formation of ions.

A covalent bond is a type of chemical bond where two atoms share one or more pairs of electrons.

Valence electrons are the electrons in the outermost shell of an atom that are involved in forming bonds.

Nitrogen, which is in group 15, gains three electrons to become a negatively charged ion (N^3-).

In an ionic bond, valence electrons are transferred from one atom to another.

Elements are pure substances made of only one type of atom, while compounds are substances formed from two or more different types of atoms bonded together.

A polar covalent bond is a type of covalent bond where the electrons are shared unequally between the two atoms, resulting in a slight charge.

A metallic bond is a type of bond found in metals where electrons are shared among a lattice of metal atoms, allowing for conductivity.
