Question

Mn (Z = 25) = 15) 1p2s 2p 201Which of the following change is required so that Mn have above ground state electronic configuration​

Answer 1

Answer:

Manganese atoms have 25 electrons and the shell structure is 2.8. 13.2. The ground state electron configuration of ground state gaseous neutral manganese is [Ar]. 3d5.

Answer 2

Answer:

    1s³ 1p⁹ 2s³ 2d¹ is a possibble when value of l=0 to n

          n=1 ⇒ l=0 ,l=1

when, n=2 ⇒ l=0 l=1 l=2

this configuration is possible when each orbital as 3 electrons.

2d ( n+l =4) is filled before 3s (n + l = 3 )  

principal quantum number (n) = shell

azimuthal quantum number (l) = sub shell

magnetic quantum nymber (m) = orbirtal

spin quantum number (s) = spin of electron.
