Verified step by step guidance1
Understand that the outermost shell of an atom refers to the highest energy level that contains electrons, also known as the valence shell.
Recall that electrons in the outermost shell are called valence electrons, which are responsible for chemical bonding and reactivity.
Recognize that core electrons are those found in inner shells, closer to the nucleus, and are not in the outermost shell.
Note that protons and neutrons are subatomic particles located in the nucleus, not in any electron shell.
Conclude that the particles found in the outermost shell (energy level) of an atom are valence electrons.
