full electron configuration for P
1s22s22p63s23p3
possible ml values for l=2
-2, -1, 0, 1, 2
bond angles of tetrahedral
109.5
All IMFs in H2S
LDF
type of solid with low melting point and insoluble in water

lithium
geometry of SF2
bent
All IMFs in NH3
LDF, d-d, H bond
Type of solid with intermediate melting point and soluble in water but doesn't conduct electricity
polar covalent
Short hand configuration for bohrium (element 107)
[Rn]7s25f146d5
identify the element: n = 4, l = 2, ml = 2, ms = +1/2
Tc
geometry of ICl4-
square planar
Molecule with the highest boiling point: CCl4, CH4, CF4, CBr4
APE
A: CBr4
P: because all 4 molecules have only LDF (they are all symmetrical) but CBr4 is the biggest (Br has a higher molecular weight than Cl, H, or F)
E: Larger molecules have stronger LDFs, so it takes more energy to separate the molecules
Type of solid with very high boiling points and insoluble in most liquids
Covalent network
Short hand electron configuration for chromium
[Ar]4s13d5
all 4 quantum numbers for iodine
n=5, l=1, ml = 0, ms = -1/2
geometry of SeCl4
seesaw
Which are soluble in water (list all): XeF4, SF4, CF4, NH3, BH3
APE
A: SF4, NH3
P: both are polar (delta EN 0.5-1.7)
E: like dissolves like, so since water is polar, polar solutes will dissolve in water
Type of solid that is insoluble in water and conducts electricity in the solid state
metallic
