Question

Atomic number of Manganese is 25.
Write the subshell electronic configuration of the positive ion in MnO2​

Answer 1

Answer:

Explanation:

Manganese has atomic number 25, meaning its atoms have 25 protons in their nuclei. A neutral manganese atom also has 25 electrons. However, the manganese 3+ ion, Mn3+, has 22 electrons. This gives it 3 more protons than electrons, which gives it the 3+ charge.

The electron configuration in noble gas shorthand for a neutral Mn atom is [Ar]3d54s2. The electron configuration for a Mn3+ ion is [Ar]3d4. The two 4s valence electrons and one 3d electron is removed.

Answer 2

Answer:

Atomic number of Mn is 25. Write the subshell electronic configuration of Mn"
