- atomic radius
- one half of the distance between the nuclei of two atoms of the same element when the atoms are joined
- alkali metals
- group 1A elements
- anion
- an ion with a negative charge
- cation
- an ion with a positive charge
- ionization energy
- the energy required to remove an electron from an atom
- ion
- an atom or group of atoms that has a positive or negative charge
- alkaline earth metals
- group 2A elements
- nonmetals
- poor conductors of heat and electric current
- inner transition metal
- highest occupied s sub level and nearly f sub level
- Metals
- good conductors of heat and electric current
- metalloid
- generally has properties that are similar to those of metals and nonmetals
- transition metal
- group B elements, the highest occupied s sub level and nearly d sublevel
- noble gases
- elements in group 8A
- Periodic Law
- when elements are arranged in order of increasing atomic number and periodic repetition of their physical and chemical properties
- halogens
- nonmetals group 7A
- electronegativity
- the ability of an atom of an element to attract electrons when the atom is in a compound
- representative elements
- group 1A to 7A because they display a wide range of physical and chemical properties
