Ionisation Energy Flashcards
1
Q
What happens to 1st ie down group 2
A
Decreases
2
Q
Why does first ie decrease down group 2
A
Extra shells added
More sheilding so weaker attraction between n and outer shell
Outer e- further away
Easier to lose e- so less energy needed
3
Q
Shielding down group 2
A
Increases
Causing weaker attraction between nucleus and outer shell electrons l.
4
Q
Outer shell electrons
A
Further away from nucleus
Weakens attraction
5
Q
Number of protons
A
Increase
