the highest valency-Al
largest atomic radius-Na
Maximum reactivity-Na
largest atomic radius-Na
Maximum reactivity-Na
Can you please help me with the justification?
Na has more atomic radius, because the protons don't attract it with a great force as in 2&3grp
reactivity is the tendency to readily gain or loose electrons
as Na has valency 1, it is easier for it to give electrons than the other two
hope this helps;)
Thanks :")

Ya
aluminium has highest valency which is 3 because it's electronic configuration is 2,8,3,.
And the other two?
na has less nuclear charge than other so it has more atomic radius
and Na has less electron in its outermost she'll so it loose electron rapidly. so it is more reactive
Thank you :)))
