Which of the following represents the ground state electron configuration for the Mn3+ ion? (Atomic number Mn = 25) 1s2 2s22p6 3
V125BC [204]

Answer:

1s^22s^22p^63s^23p^63d^{4}

Explanation:

Manganese is the element of group 7 and forth period. The atomic number of Manganese is 25 and the symbol of the element is Mn.

The electronic configuration of the element, manganese is -  

1s^22s^22p^63s^23p^63d^{5}4s^2

To form Mn^{3+}, it will lose 3 electrons from the valence electrons and thus the configuration of the ion is:-

1s^22s^22p^63s^23p^63d^{4}
