Write the electronic configurations for mn, mn2+, mn4+, mn6+, and mn7+

The electronic configurations are written below.

Explanation:

Electronic configuration is defined as the representation of electrons around the nucleus of an atom.  Number of electrons in an atom is determined by the atomic number of that atom.

Atomic number is defined as the number of protons or electrons that are present in a neutral atom.

Atomic number = number of protons = number of electrons

We know that:

Atomic number of Manganese = 25 = Number of protons

Number of electrons = Number of protons - charge

Number of electrons = 25

Electronic configuration of Mn :

Number of electron = 25 - (+2) = 23

Electronic configuration of

Number of electron = 25 - (+4) = 21

Electronic configuration of

Number of electron = 25 - (+6) = 19

Electronic configuration of

Number of electron = 25 - (+7) = 18

Electronic configuration of

Hence, the electronic configurations are written above.

dynamic equilibrium is the answer.
