Group 1, 7, 0 Flashcards
How many electrons are in the outer shell of Group 1?
1
As you go down the group the reactivity…
increases
Why is K more reactive than L?
Greater atomic radius, more electron shielding, easier to lose outer shell electrons
the reactivity of Group 7
as you go up the group it is more reactive
Why is F more reactive than Br?
F has a smaller radius , F has less electron shielding, easier to gain outer shell electron
Why are there higher boiling points as you go down Group 7?
There are more electrons which means more energy to overcome the intermolecular forces
What is Group 0 referred to?
The noble gases
Features of Group 0
they are stable, full outer shell of electrons and unreactive
Why are there higher boiling points as you go down Group 0?
More electrons which means more energy to over come the intermolecular forces
