D. all of its valence electrons are in the 3p orbital. 2. Some of these elements you mention are not typically tested due to their variable behavior. Chromium 2,8,13,1. The "II" means it has 2 valence electrons. Potassium, chromium, and copper are the only elements in the fourth period that have one electron in the outermost shell. ... You may have an easy way to know the number of electrons in a neutral atom, ... Wild electron configurations also mean you have a good chance at a variety of valence numbers. Physical Properties of Chromium. Chromium. Therefore, valency of Chromium is 2. Electron configuration was first conceived under the Bohr model of the atom, and it is still common to speak of shells and subshells despite the advances in understanding of the quantum-mechanical nature of electrons.. An electron shell is the set of allowed states that share the same principal quantum number, n (the number before the letter in the orbital label), that electrons may occupy.
