CHEM REVIEWER

increases as you move down a group in the periodic table

metallic character

ideal gas law formula

PV = nRT

highest electronegativity

fluorine

according to dalton’s law of partial pressure, the total pressure of a gas mixture is equal to

the sum of partial pressures

largest atomic size

sodium

explains that electrons fill from the lowest to highest energy level

Aufbau principle

the ability of an atom to attract electrons

electronegativity

no two electrons in an atom can have the same set of four quantum numbers

Pauli exclusion principle

the motion and behavior of gas particles

kinetic molecular theory

lighter gases diffuse faster than heavier gases

graham’s law

the outermost electrons involved in bonding

valence electron

has a full valence shell

noble gases

the ionization energy of an element is the energy required to

remove an electron

according to the kinetic molecular theory, gas particles move in

straight lines until they collide

states that each orbital in a sublevel must be singly occupied

hund’s rule

standard temperature and pressure

22.4 L

does not usually have high ionization energy and low reactivity

metals

gases with lower masses diffuse faster

Graham’s law of diffusion

what happens to the ionization energy as you move down a group in the periodic table?

decreases

high electronegativity

nonmetals

as you go down a periodic table, atomic radius generally

increases

formed when an atom loses one or more electrons

cation
