Chemistry Final Exam Review ACTUAL UPDATED QUESTIONS AND CORRECT
ANSWERS
electron configuration the arrangement of electrons in an atom
, period A horizontal row of elements in the periodic table
group A column on the periodic table
atomic radius Size of the atom. Increases in size from more shells or if atom gains electrons
(anion). Decreases in size if atom loses electrons (cation) or less shells.
ionization energy The amount of energy required to remove an electron from an atom
electronegativity tendency of atoms to attract electrons to themselves when they bond.
ion size positive is smallest and negative is biggest radius
Cation A positively charged ion
anion A negatively charged ion
catalyst a substance that initiates or accelerates a chemical reaction without itself being
affected
