How does the radial probability plot and electron probability distribution look like
Goes up (1/4) and back down
how does the p orbitals look like?
two lobes and nucleus is on a plane that divides the lobes
how does d orbitals look like?
four lobes and one of them (dz2) has two and a ring
What are the 3 known electron configuaration anomolies
Cr, Cu, Mo
Chromium, Copper, Molybednum
diamagnetism
all of electrons are paired
paramagnetism
atoms with unpaired electrons
What 2 things make an atom bigger
NOT THE TREND, THE REASON
decreasing ZEFF, increasing electron electron repulsion making e- cloud bigger
What groups are the anomolies of IE in?
Group 3, 6
What groups is electron affinity +
and why
2,5 (just nitrogen), 8
energy must be added to add an additional electron

Ionic Compounds
- physical state
- melting and boiling point
- solubility in water
- Electrical Conductivity
- Exist as solids at room temp
- high melting and boiling
- dissolve in water
- do not conduct electricity in wolid state, does conduct in molten state
