3.4 Quantum Numbers

Question 1

n

Answer 1

primary quantum number, energy level and size of orbital, as n increase so does energy and size of orbital

Question 2

l

Answer 2

secondary quantum number/angular 3d shape of orbital and sublevel/subshells, energy increases from

Question 3

m sub l

Answer 3

orientation of orbital, magnetic quantum number,

Question 4

m sub s

Answer 4

spin of electron (1/2, spin up, clockwise)

Question 5

nodes

Answer 5

spaces between energy levels where there is no probability of finding an electron

Question 6

paramagnetism

Answer 6

a week attraction to a strong magnet, related to msub s, unpaired electrons with the same spin generate a weak magnetic field in individual atoms of aluminum and platinum

Question 7

Hund’s rule

Answer 7

electrons must be distributed among orbitals of equal energy, electrons occupy seperate orbitals with parralel spins and remain unpaired when possible

Question 8

ferrimagnetism

Answer 8

very strong magnetism create by atoms of iron, nickel and cobalt, unpaired electrions alighn in the same dierction and become a permanent magnet when an external magnetic field is present

Question 9

exeptions

Answer 9

Cr: (Ar) 4s13d5
Cu: (Ar) 4s13d10
Au: (Xe)6s14f145d10
