A
increases
2
Q
finish the sentence:
the reactivity ? as you go up group 1 alkali metals
A
decreases
3
Q
why does reactivity increase as you go down group 1?
A
outer electrons are further away from the nucleus which reduces nuclear attraction, making it easier for alkali metals to lose electrons
4
Q

A
the outer most electrons are closer to the nucleus and have stronger nuclear attraction, making it easier for halogens to gain electrons
