Explanation:
Hey there!!
We generally use s,p,d,f formula.
So, let's do with it.
1.Neon
Atomic no. = 10
So, Its electronic configuration is;
[tex] = 1 {s}^{2} .2 {s}^{2} 2 {p}^{6} [/tex]
2.Zinc.
Atomic no. = 30
So, it's electronic configuration is;
[tex] = 1 {s}^{2} 2 {s}^{2} 2 {p}^{6} 3 {s}^{2} 3 {p}^{6} 4 {s}^{2} 3 {d}^{10} [/tex]
3. Tungsten.
Atomic no. = 74.
So, it's electronic configuration is;
[tex] = 1 {s}^{2} 2 {s}^{2} 2 {p}^{6} 3 {s}^{2} 3 {p}^{6} 4 {s}^{2} 3 {d}^{10}4 {p}^{6} 5 {s}^{2} 4 {d}^{10} 5 {p}^{6} 6 {s}^{2} 4 {f}^{14} 5 {d}^{4} [/tex]
4. Magnesium.
Atomic no. = 12
So, the electronic configuration is ;
[tex] = 1 {s}^{2} 2 {s}^{2} 2 {p}^{6}3 {s}^{2} [/tex]
Hope it helps...
