Which of the following has largest atomic size? a.Li b.Na c.K d.Al?
It's obviously K !!!
Since Li, Na, K lies in the same group in the periodic table nd the atomic size increase down the group due to addition of new shell ...
And although Na nd Al lies in the same period nd have same number of shells but Al has more more no of electrons i.e. 13 electrons nd Na has 11 electrons due to which the nucleus will attract the electrons towards itself so henceforth it's size will decrease , so since no of electrons is more in Al so it's size will decrease more than Na so in that case the atomic size of Na will be more than that of Al !!!
