Expert Solution

Answer to Problem 2.84P

The number of electrons in outermost shell of Se is 6.

Explanation of Solution

Electrons are distributed in the orbitals of the subshell. The specific region of space in which the movement of electrons is confined is said to be shells which are divided into subshells and are s-, p-, d-, and f-. Among these subshells, the electrons are grouped as orbitals.

The number of electrons that these subshells can hold is:

s-block - 2.

p-block - 6.

d-block - 10.

f-block - 14.

The electronic configuration of Se (34) is 1s² 2s² 2p⁶ 3s² 3p⁶ 3d¹⁰ 4s² 4p⁴.

On the basis of above electronic configuration, the outermost shell or valence shell is 4s 4p which contains six electrons.

Thus, number of electrons in outermost shell of Se is 6.
