Question

Compare the electronic configuration of mn4+

Answer 1

Answer:

1s2 2s2 2p6 3s2 3p6 4s2 3d1

Ok Mn has 25 electrons but you have +4 ion so that means you lost 4 electrons so your electron config must show 21 electrons. On the notation above , the first number is the energy level, the letter is the shell where the electron is located and the number is the number of electrons in the shell.

Soooo now look at the periodic table and follow the electron config, you will see how it systematically maps out where you are on the periodic table with the number of electrons present. You should end up at element 21 Sc because you have 21 electrons.

HOPE IT HELPS ^_^
