susunlah kelompok atom-atomdan ion-ion berikut menurut kenaikan ukurannya a.Na,Ne,Na b.k,Ar,CL c.N,O,C d.O,Ne,Mg. terima kasih

*a
11Na = 2 8 1
10Ne = 2 8
rNe < rNa

*b
19K = 2 8 8 1
18Ar = 2 8 8
17Cl = 2 8 7
rAr < rCl < rK

*c
7N = 2 5
8O = 2 6
6C = 2 4
rO < rN < rC

*d
8O = 2 6
10Ne = 2 8
12Mg = 2 8 2
rNe < rO < rMg
