Does Cr have 2 valence electrons?

Does Cr have 2 valence electrons?

Chromium has multiple valences, and this is due to the fact that it has three oxidation states of +6, +3 and +2. Chromium lies in Group 6 of the Periodic Table ; i.e. there are 6 valence electrons.

Does Cr have 24 electrons?

Chromium is the first element in the sixth column of the periodic table. It is classified as a transition metal. Chromium atoms have 24 electrons and 24 protons with the most abundant isotope having 28 neutrons.

Why is chromium an exception with electron configuration?

Elements such as copper and chromium are exceptions because their electrons fill and half-fill two subshells, with some electrons in the higher energy level shells.

How many electrons are in Cr?

24 electrons
In order to write the Chromium electron configuration we first need to know the number of electrons for the Cr atom (there are 24 electrons).
