Question

Number of electrons present in M-shell of an
element, M (atomic number = 26) in its M3+ state
will be
(1) Zero
(2) 8
(3) 13
(4) 14​

Answer 1

Answer:13 electrons

Explanation:

2 electrons in 3s + 6e- in 3p + 5e- in 3d

Answer 2

Answer:

13

Explanation:

since atomic number (Z = 26)

mean it consist 26 protons and 26 electrons And its K L M notations is 2 , 8 , 16

now in M 3+ state it loses 3 electrons  

so electrons present will be 26 - 3 = 23

so  electrons will be lost from M subshell so  M = 13
