Molarity (M)
(amount (mol) of solute)/(volume (L) of solution)
Molality(m)
(amount(mol) of solute)/(mass(kg)of solvent)
Parts by mass
Mass of solute/mass of solution
Parts by volume
volume of solute/volume of solution
Mole Fraction (X)
(amount (mol) of solute)/(amount (mol) of solute+amount (mol) of solvent)

ionization energy
energy (kJ) required for the complete removal of 1 mol of electrons from 1 mol of gaseous atoms or ions
Pattern of Ionization Energy
As size decrases, it takes more energy to remove an electron
electron affinity
energy change (kJ) accompanying the addition of 1 mol of electrons to 1 mol of gaseous atoms or ions
