halogens Flashcards
1
Q
why does reactivity decrease as you go down the halogens
A
because electrons are more easily gained, due to there being less distance between nucleus and outer shell electrons
2
Q
what happens to melting and boiling points as you go down the halogens
A
they increase
3
Q
why do the melting and boiling points of halogens increase as you go down the group
A
molecule size increases and they trend from gas–>liquid–>solid
4
Q
what are all halogen molecules
A
diatomic, eg. X2 or O2
5
Q
what will happen if a more reactive halogen and a less reactive halogen are put in solution together
A
the more reactive halogen will displace the less reactive solution
6
Q
what happens to reactivity as you go down the halogens
A
it decreases
