Which type of electrons are located in the outermost energy level of the electron cloud and possess the most energy?

• A. Protons
• B. Valence electrons
• C. Neutrons
• D. Core electrons

Answer: (B)

Verified step by step guidance

1. Understand that electrons in an atom are arranged in energy levels or shells around the nucleus.
2. Recognize that the outermost energy level of an atom is called the valence shell.
3. Identify that electrons located in this outermost shell are called valence electrons.
4. Know that valence electrons have higher energy compared to electrons in inner shells (core electrons) because they are farther from the nucleus.
5. Recall that protons and neutrons are subatomic particles found in the nucleus, not in the electron cloud, so they are not involved in this context.
