Question

write electronic configuration of A+³(atomic number 44). Also find all the four quantum numbers of its 31st electron​

Answer 1

Because the atomic number is 44 it has 44e-

But since it has +3 charge 3e- are missing and hence only 44-3 = 41e-

$1 {s}^{2} 2 {s}^{2}2 {p}^{6} 3 {s}^{2}3 {p}^{6} 3 {d}^{10} 4s {}^{2} 4p {}^{6} 4d {}^{4} 5s {}^{1}$

☺️here is your answer Abhishek ☺️

because the atomic number is 44...it has 44e-...

but since it has+3 charge..3e-are missing....and only 44-3 =41e-
