Question

the size of aluminium 3+ is lower than that of flourine​

Answer 1

Answer:

al 3+ is smaller in size than flourine

Explanation:

because as al losses 3 of its electrons so it resemble the configuration of fluorine .

so , its atomic size decrease s due to lose of electrons

Answer 2

Al+3 loose 3 electrone from its last orbit

Hence electronic configuration of flourine is 1s*2 2s*2 2p*5

Al+3 1s*2 2s*2 2p*6 its is stable

So the size of al+3 is lower then Flourine
