Elements of the Periodic Table
15
representative elements : the highest occupied s and p sublevels are partially filled.
electronegativity : measures the ability of an atom to attract electrons when the atom is in a compound
atomic radius : one half the distance between the nuclei of two atoms of the same element when the atoms are joined.
metals : good conductors of heat and electric current
ionization energy : energy required to remove an electron from an atom
cation : positively charged ion
noble gas : elements in which the highest occupied s and p sublevels are filled.
alkali metals : group 1A elements
inner transition metals : the highest occupied s sublevel and a nearby f sublevel contain electrons
nonmetals : poor conductors of heat and electric current
ionic radius : decreases for cations and anions from left to right across a period
ion : an atom or group of atoms that has a positive or negative charge
Group 2A : metals having only 2 electrons in the highest occupied energy level
transition metal : the highest occupied s sublevel and a nearby d sublevel contain electrons
halogens : nonmetals of group 7A
anion : negatively charged ion
