21
Q

What is ionization energy?

A

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

22
Q

What is electron affinity?

A

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

23
Q

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

A

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

24
Q

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

A

Ca+ → Ca<span>2+</span> + e- delta H is always positive

25
Q

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

A

Ca<span>2+</span> → Ca3<span>+</span> + e- delta H is always positive

26
Q

Write an equation that describes the electron affinity of oxygen.

A

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

27
Q

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

A

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

28
Q

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

A

Atom gets smaller

29
Q

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

A

IE get larger

30
Q

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

A

EA get more negative

31
Q

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

A

EA get more positive

32
Q

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

A

IE goes down

33
Q

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

A

Atomic radius gets larger

34
Q

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

A

smaller - fewer electron - electron repulsions

35
Q

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

A

larger - more electron - electron repulsions

36
Q

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

A

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.
