Question

12. Number of electrons present in M-shell of an
element, M (atomic number = 26) in its M3+ state
will be
​

Answer 1

Answer:

8 electrons

Explanation:

the configuration will be- 2,8,8,2,6 for atom

for m 3+- 2,8,8,2,3

in m shell(3rd shell) there are 8 electrons

Answer 2

Answer:

M shell represents the third shell. no of electrons in element M =26

no of electrons in M 3+ = 23

electronic configuration of M 3+ =

1s2 2s2 2p6 3s2 3p6 3d5

hence , no of electrons in M shell = 13 electrons
