Electron Worksheet #1 Answer Key - The valence electrons are the electrons in the outermost energy level. Elements in groups ia to iiia do not follow the octet rule and have less than eight electrons in the final formula. 2) using octet rule, arrange the electrons to its orbital shells based on electron configuration. Write the electron configuration for the following ions:

Indicate whether the following elements will gain or lose electrons to get a full outer shell, and how many electrons they will need to gain or lose. As2− a s 2 −. Be2+ b e 2 +.

The Easiest And Most Reliable Technique For Writing Electron Configurations Is To Use The Periodic Table As Your Guide.

An electron configuration is a shorthand notation that is used to describe the locations of all of the electrons in an atom. Subshells have only 1 orbital, 2 electrons per orbital = 2 electrons max. The s orbital is located in the first energy shell (energy shell 1).
