Ionisation Energy

Question 1

Nuclear charge affect

Answer 1

more protons -> more attraction

Question 2

affect of distance

Answer 2

the further the electron the weaker the attraction

Question 3

shielding of nuclear charge affect

Answer 3

electron in outer shell
repelled by electrons in inner shells
which weakens attraction

Question 4

Mg and Al

Answer 4

3p is higher in energy
so electrons are slightly shielded by 3s
so easier to remove e- from 3p sub shell

Question 5

P and S

Answer 5

S has 4 e- in 3p
means its starting to fill up doubly
repulsion between paired electrons
easier to remove
