Part A Arrange the compounds in order of decreasing magnitude of Ilattice energy: LiBr, KI, and CaO. Rank from largest to smallest. To rank items as equivalent, overlap them. Reset Help Largest Smallest The correct ranking cannot be determined. Submit My Answers Give Up
Answer
A)
lattice energy --> strongest for Oxygen,
if alkali metal + halide, then the smaller the metal, the
strogner the lattice
therefore
LiBr > KI
then
CaO >> LiBR > KI
A)
metal = brittle, ahrd, will conduct e-, high Melting points
nonmetal --> low BP, will not conduct e-
semimetal --> both properties
therefore
O = nonmetal
Xe= nonmetal ( noble gas)
As = metalloid, has properties of both species
Mg = metal
Zn = metal,
Pb = metal
