Question

which one has the bigger size and (11 )or CL (17 )& CL(17) or F (9)
and also mention why ?​

Answer 1

Answer:

Na(11)

Explanation:

sodium has a greater atomic size because as you go down a group atomic size increase as electron is added to a new shell and hence you can eliminate F(9)

Similarly, as yo go from left to right of a periodic table the atomic size decreases as you add the electron into the same shell and nuclear attractions on the valence electron will increase and hence the atomic size reduces. so u can eliminate Cl(17)
