WebMar 21, 2024 · This first shell has only one subshell, which is labeled s and can hold a maximum of 2 electrons. We combine the shell and subshell labels when referring to the organization of electrons about a nucleus and use a superscript to indicate how many electrons are in a subshell. WebThe maximum electrons holding capacity in M orbit is 2n 2 = 2 × 3 2 = 18. n=4 for N orbit. The maximum electrons holding capacity in N orbit is 2n 2 = 2 × 4 2 = 32. Therefore, the maximum electron holding capacity in the first shell is two, the second shell is eight and the 3rd shell can have a maximum of eighteen electrons. WebShell number one can only hold 2 electrons, shell two can hold 8, and for the first eighteen elements shell three can hold a maximum of eight electrons.
