CHEM 1201 Lecture Notes - Lecture 16: Lone Pair, Potassium Bromide, Lattice Energy
Document Summary
Warmup: circle all the apply, more than one may be needed. Ionization energy increases to the a. ) left b. ) right c. ) top d. ) bottom. Electronegativity increases to the a. ) left b. ) right c. ) top d. ) bottom. Atomic radii increases to the . a. ) left b. ) right c. ) top d. ) bottom. Effective nuclear charge increases . a. ) across a period to the left b. ) across a period to the right. Metallic characteristics decrease to the . a. ) left b. ) right c. ) top d. ) bottom. Isoelectric atoms have a radius that increases as . a. ) atomic number increases b. ) atomic number decreases c. ) electron number increases d. ) electron number decreases. Lattice energy: ionic molecules are attracted to each other due to their electric charge (cations. + anions) it directly relates to coulombs law: Lattice energy is: the amount of energy required to completely separate a mole of a solid ionic compound into its gaseous ions.
