So for scandium the 1 st and 2 nd electron must be in 1s orbital, the 3 rd and 4 th in the 2s, the 5 th through 10 th in the 2p orbitals, etc. Just replace this portion of zinc's electron notation with Argon's chemical symbol in brackets ([Ar].) The material on this site can not be reproduced, distributed, transmitted, cached or otherwise used, except with prior written permission of Multiply. Electron levels are filled in the order of the lowest energy level first. M shell – 7 electrons. However, notice that 1s 2 2s 2 2p 6 3s 2 3p 6 is the configuration for Argon, a noble gas. Even though its electron configuration is a bit different, scandium still wants to bond with those three extra electrons, no matter what shell they are in. Elements prefer to stay at the lowest energy level possible. The alkaline earth metal magnesium (atomic number 12), with its 12 electrons in a [Ne]3s 2 configuration, is analogous to its family member beryllium, [He]2s 2.Both atoms have a filled s subshell outside their filled inner shells. For example, In K shell atmost 2 electrons can be there. According to the aufbau diagram the configuration should be 1s 2, 2s 2, 2p 6, 3s 2, 3p 6, 4s 2, 3d 1 and indeed it is.

Scandium represents the first of the transition elements, corresponding to the filling of the d orbitals. (c) The valency of X is 2 because it can acquire stable gas configuration by losing 2 electrons. But conventional wisdom claims that the final electron to enter the atom of scandium is a 3d electron, when experiments indicate that the 3d orbital is filled before the 4s orbital. The fifth period with n = 5 starts by filling the level 5s. The chemical, metallurgical, and physical behaviours of the rare earths are governed by the electron configuration of these elements. Calcium's electron configuration is [Ar]4s 2. The electron configuration of an atom is very important as it helps to predict the chemical, electrical and magnetic behavior of substance. This page shows the electron configurations of the neutral gaseous atoms in their ground states. When you work out the electronic structures of the first transition series (from scandium to zinc) using the Aufbau Principle, you do it on the basis that the 3d orbitals have a higher energy than the 4s orbital. Why is the electronic configuration of potassium 2,8,8,1 and not 2,8,9, If you say that's bcoz of octet rule then why is the electronic configuration of Chromium 2,8,13,1 - Chemistry - Consider for example this data. ... 17M.2.hl.TZ2.2b.iii: Explain why iron forms many different coloured complex ions.
