the highest valency-Al
largest atomic radius-Na
Maximum reactivity-Na

aninaakumarp1ofjr: Can you please help me with the justification?

Anonymous: Na has more atomic radius, because the protons don't attract it with a great force as in 2&3grp

Anonymous: reactivity is the tendency to readily gain or loose electrons

Anonymous: as Na has valency 1, it is easier for it to give electrons than the other two

Anonymous: hope this helps;)

chirag8874695183: Ya

chirag8874695183: aluminium has highest valency which is 3 because it's electronic configuration is 2,8,3,.

aninaakumarp1ofjr: And the other two?

chirag8874695183: na has less nuclear charge than other so it has more atomic radius

chirag8874695183: and Na has less electron in its outermost she'll so it loose electron rapidly. so it is more reactive

aninaakumarp1ofjr: Thank you :)))
