Why do halogens have 7 valence electrons? – Quora

In each halogen the math then always leaves 7 electrons for the p sublevel equal to the period number for that element. So its basically the result of the protons/electron balance and the sequence of filling of the levels, sublevels and orbitals.

How many Valence Electrons does Manganese have? – Overnight Writers

Apr 28, 2022So, we will have to rewrite the electrone configuration in the standard way, which means the way that the electrons be around the nucleus: ##1s^2# 2s^2# 2p^6## ##3s^2## ##3p^6## ##3d^5#4s^2## So, when the electrones leave the atom the leave in the above order, with the electrons in the 4s orbital first. Therefore Mn has 2 valence …

Manganese(VII) oxidation state – Chemistry Stack Exchange

Manganese (VII) oxidation state. A transition element is one which forms one or more stable ions which have partially filled d-orbitals. Manganese (Mn) could have an oxidation state of 7+, which means that it will lose all of the 3 d X 5 and 4 s X 2 electrons. So how could it make a 7+ ion in that case (which means that it will lose all of the …
