21

What is ionization energy?

Energy required to remove an electron from an atom or ion (always positive) 

22

What is electron affinity?

Energy change that occurs when an atom or ion gains an electrons - Often negative but can be positive 

23

Write an equation that describes the 1st ionization energy for Calcium

Ca → Ca+ + e-  delta H is always positive

24

Write an equation that describes the 2nd ionization energy for Calcium

Ca+ → Ca2+ + e-  delta H is always positive

25

Write an equation that describes the 3rd ionization energy for Calcium

Ca2+ → Ca3+ + e-  delta H is always positive

26

Write an equation that describes the electron affinity of oxygen.

O + e- → O-  delta H is usually negative but can be positive

27

Write an equation that describes the 2nd electron affinity of oxygen.

O- + e- → O2-  delta H is usually negative but can be positive

28

What happens to atomic radius as you move across a period?

Atom gets smaller

29

What happens to ionization energy (IE) as you move across a period?

IE get larger

30

What happens to electron affinity (EA) as you move across a period?

EA get more negative

31

What happens to electron affinity (EA) as you move down a group?

EA get more positive

32

What happens to ionization energy (IE) as you move down a group?

IE goes down

33

What happens to atomic radius as you move down a group?

Atomic radius gets larger

34

A positive ion is (larger / smaller) than its neutral parent atom.

smaller - fewer electron - electron repulsions

35

A negative ion is (larger / smaller) than its neutral parent atom.

larger - more electron - electron repulsions

36

For a pair of isoelectronic ions, the more negative ion is (larger / smaller) than the more positive ion.

larger - more positive ion has a larger nuclear charge so it pulls its electrons in more effectively than the more negative ion which has a smaller nuclear charge.
