WebApr 30, 2024 · Chromium exhibits a wide range of possible oxidation states, of which the +3 and +6 states are the most commonly observed in its compounds. Furthermore, … Chromium is the fourth transition metal found on the periodic table, and has an electron configuration of [Ar] 3d 4s . It is also the first element in the periodic table whose ground-state electron configuration violates the Aufbau principle. This occurs again later in the periodic table with other elements and their electron configurations, such as copper, niobium, and molybdenum. This occurs because electrons in the same orbital repel each other due to their like charges. In t…

The oxidation state of the element represents the charge possessed by an atom due to the loss or ... 3d5 4s2. The two electrons in the 4s orbital are obvious valence electrons, so a valence state of 2+ is possible. Reply. nirjhara ... WebTherefore, chromium ion (Cr 2+) has a total of twelve valence electrons. Cr – 3e – → Cr 3+. On the other hand, The electron configuration of chromium ion (Cr 3+) is 1s 2 2s 2 2p 6 3s 2 3p 6 3d 3. This electron configuration shows that chromium ion (Cr 3+) has three shells and the last shell has eleven electrons. tso wallpaper
