[Answer] What shell has a highest energy?

Answer: The valence shell

Most relevant text from all around the web:

What shell has a highest energy? Electrons with the highest energy levels exist in the outermost shell of an atom and are relatively loosely bound to the atom. This outermost shell is known as the valance shell and electrons in this shell are called valance electrons. A completed outermost shell has valance of zero. Fri Mar 18 2011 · 4f subshell has the highest energy. A f subshell has the highest energy among all the subshells in any shell. The valence shell is the outermost shell of an atom. Valence electrons in s- and p-elements reside in this shell. Such elements with complete valence shells (noble gases) are the least chemically reactive while those with only one electron in their valence shells (alkali metals with the exception of hydrogen) or just missing one electron from having a complete shell (halogens) are the most reactive. Hydrogen being the only element which has one electron in its valence shell but is also just missing one electron from havin… L shell has higher energy as a result of in keeping with Bohr’s theory the shell that is nearer to Compare Electric Plans nucleus has lower energy and therefore the shell that is … The lowest energy level (the K shell ) can only be occupied by two...
