Lattice energy

Question 1

Ionic bonding

Answer 1

transfer of electrons and usually observed when metal bonds to nonmetal

Question 2

lattice energy

Answer 2

energy released when 1 mole of ionic solid forms from its free ions in the gas phase

Question 3

magnitude of lattice energy

Answer 3

strength of ionic interactions; influences properties of melting point, hardness, and solubility

lattice energy/attraction increases as ionic charge increases

lattice energy/attraction increases as ionic size decreases

Question 4

periodic trends in lattice energy

Answer 4

lattice energy decreases down a group

increases across the period

smaller distances between elements on periodic table can also create higher energy (vs. bigger distances)
