Verified step by step guidance1
Understand the structure of an atom: it consists of a nucleus containing protons and neutrons, surrounded by electrons arranged in energy levels or shells.
Recall that protons are positively charged particles located in the nucleus, and neutrons are neutral particles also in the nucleus.
Recognize that electrons are negatively charged particles that occupy different energy levels around the nucleus.
Identify that electrons in the outermost energy level of an atom are called valence electrons; these are responsible for chemical bonding and reactivity.
Conclude that the term describing negatively charged particles in the outermost energy levels is 'valence electrons'.
