Ionization energy: the amount of energy needed to remove an electron from an atom.

Electronegativity : an element's relative ability to attract electrons in a chemical bond

Representative elements: The elements in groups 1, 2, and 13 to 18 of the periodic table are often referred to as the main group, or representative elements ( s and p create it)

Transition metals : are the elements found in groups 3 to 12 of the periodic table. They are also known as the d-block elements because their valence electrons are typically found in the d sublevel. Most transition elements are metals

Valence electrons : electrons on the last energy level

anion : when an atom gains electrons

Cation : when an atom lose electrons

Group : vertical vertical column of elements in the periodic table

Period : horizontal row of elements in the periodic table

The periodic law simply means that when you arrange elements by their atomic number, their properties repeat in a predictable pattern

Isoelectronic : have the same electronic structure and the same number of valence electrons
