2

Question 2

maximum number of electrons in a shell formula

Answer 2

2n^2

Question 3

atomic orbital

Answer 3

region around nucleus that can hold up to two electrons, with opposite spins

Question 4

4 types of orbitals

Answer 4

s-,p-,d-,f-orbitals

Question 5

what shape is s-orbitals

Answer 5

sphere

Question 6

what shape is p-orbitals (single and clustered)

• (name all three)
• the orbitals are ____ to each other

Answer 6

• dumbell/ flower shape
• horizontal {Px}, vertical {Py} and diagonal {Pz}
• 90 degrees

Question 7

order of sub shell filling

Answer 7

1s>2s>2p>3s>3p>4s>3d>4p>5s>4d>5p

Question 8

rule to remember with the order

Answer 8

3d ishigher in energy than 4s and so gets filled and emptied after the 4s

Question 9

s has_ orbitals and holds up to _ electrons

Answer 9

1, 2

Question 10

p has_ orbitals and holds up to _ electrons

Answer 10

3, (2x3) 6

Question 11

d has_ orbitals and holds up to __ electrons

Answer 11

5, (2x5) 10

Question 12

• for orbitals with the same energy,
  occupation ______ before ________ due to ______ ________
• explain spin pairing

Answer 12

• singly, pairing, electron repulsion

- when 2 electrons occupy same orbital they ‘spin’ in opposite directions
