Atomic number

is the number of protons found in the nucleus of an atom of an element, determining its chemical properties and place in the periodic table.

mass number

the total number of protons and neutrons in an atom's nucleus.

ion

is an atom or molecule that has a net electrical charge due to the loss or gain of one or more electrons.

ionic charge

is the difference between the number of protons and electrons in an ion, indicating whether it is positively or negatively charged.

chemcial Bond

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

covalent

bond is a type of chemical bond formed when atoms share electrons.

anion

a negatively charged ion that has gained one or more electrons.

polyatomic ion

a charged ion composed of two or more atoms bonded together, which behaves as a single unit in chemical reactions.

NH4+

is the ammonium ion, a common polyatomic ion that carries a positive charge.
