Each p-subshell can hold a maximum of 6 electrons, so we will use 6 electrons for the 2p subshell. In general, how is the shape of the periodic table related to electron configurations. Thus, the noble gas (elements in group 8) and the alkali metal (elements in group 1) that has a similar electronic configuration are Argon and Potassium ion. Again for this same reason, inert gas is called a noble gas. Again, each s-subshell can hold a maximum of 2 electrons, so we will use 2 electrons for the 2s subshell. Predict: Positively charged protons in the nucleus of an atom are attracted to negatively Add a second electron to the first 2p orbital. The Methodology of the Social Sciences (Max Weber), Psychology (David G. Myers; C. Nathan DeWall), Business Law: Text and Cases (Kenneth W. Clarkson; Roger LeRoy Miller; Frank B.
