the quantum mechanics (model of the atom) (unit 3)

Question 1

what is an orbital filling diagram

Answer 1

the more visual way to represent the arrangement of all the electrons in a particular atom.

Question 2

what are electron configurations

Answer 2

simplifies the indication of where electrons are located in a specific atom

Question 3

what is the Pauli Exclusion Principle

Answer 3

in a sublevel each orbital fills with one electron before any orbital fills with two

Question 4

what are the principle energy levels

Answer 4

1, 2, 3, 4, 5… (before the letter)

Question 5

what are the sublevels/subshells

Answer 5

s, p, d, f

Question 6

what are the number of electrons in a subshell

Answer 6

2 (1 orb)
6 ( 3 orb)
10 (5 orb)
14 (7 orb)

Question 7

what are valence electrons

Answer 7

electrons in the highest energy level (if the same, add # of electrons together)

Question 8

paramagnetic

Answer 8

at least one unpaired electron
attracted to the magnetic field

Question 9

diamagnetic

Answer 9

all electrons are paired
repelled by the magnetic field
