Question

Number of electrons present in M-shell of an
element M with atomic number 26 in its
${m}^{? + 3}$


state
will be
(1) Zero
(2) 8
(3) 13
(4) 14​

Answer 1

Answer:

electronic configuration of element M

will be 2,8,8,8

in M +3 state it will lose 3 electrons

so its electronic configuration will be

2,8,8,5

so electrons in its M shell will be 8

hope it helps you
