Where, 3p6 indicates that the 3p subshell has 6 electrons. Since the 3s if now full well move to the 3p where well place the remaining six electrons. For this inert elements are called inert gases. Rearrange: The 4s subshell is a lower-energy subshelthan 3d, so it is filled first. Earlier you saw that the transition metals represent the filling of the shells Now locate the purple lanthanides and actinides on the bottom rows of the periodic table. If you want to do manually then follow the steps below to write shorthand electron configurations: First, find the required element on the periodic table. Just like passengers getting on a bus, electrons orbit the nuclei of atoms in particular patterns. Again, each s-subshell can hold a maximum of 2 electrons, so we will use 2 electrons for the 2s subshell. Click Check What is the electron configuration for calcium?
