Question

Write electron configuration from na to ca

Answer 1

Na: atomic number 11
$1 {s}^{2} 2 {s}^{2} 2 {p}^{6} 3 {s}^{1}$Mg:12
$1 {s}^{2} 2 {s}^{2} 2 {p}^{6} 3 {s}^{2} \\ Al:13 = 1 {s}^{2} 2 {s}^{2} 2 {p}^{6} 3 {s}^{2} \: 3 {p}^{1} \\ Si:14 = \: 1 {s}^{2} 2 {s}^{2} 2 {p}^{6} 3 {s}^{2} \: 3 {p}^{2} \\ P:15 = 1 {s}^{2} 2 {s}^{2} 2 {p}^{6} 3 {s}^{2} \: 3 {p}^{3} \\ S:16 = 1 {s}^{2} 2 {s}^{2} 2 {p}^{6} 3 {s}^{2} \: 3 {p}^{4} \\ Cl:17 = 1 {s}^{2} 2 {s}^{2} 2 {p}^{6} 3 {s}^{2} \: 3 {p}^{5} \\ Ar :18= 1 {s}^{2} 2 {s}^{2} 2 {p}^{6} 3 {s}^{2} \: 3 {p}^{6} \\ K:19 = 1 {s}^{2} 2 {s}^{2} 2 {p}^{6} 3 {s}^{2} \: 3 {p}^{6}4 {s}^{1} \\ Ca:20 = 1 {s}^{2} 2 {s}^{2} 2 {p}^{6} 3 {s}^{2} \: 3 {p}^{6} \: 4 {s}^{1}$
