Utah Esthetician State Board Practice Exam

Which statement correctly describes neutrons, protons, and electrons?

1. Neutrons are negatively charged

2. Electrons are positively charged

3. Protons are positively charged, electrons are negatively charged, and neutrons are neutrally charged

4. Protons and neutrons are both negatively charged

The correct answer is: Protons are positively charged, electrons are negatively charged, and neutrons are neutrally charged

The correct choice accurately outlines the charges associated with protons, electrons, and neutrons, which are fundamental particles found in atoms. Protons carry a positive charge, which plays a critical role in defining the identity of an element and its position on the periodic table. Electrons, in contrast, possess a negative charge and orbit the nucleus of an atom. Neutrons are electrically neutral, meaning they have no charge at all. This balanced designation of charges is essential for understanding atomic structure, chemical bonding, and how elements interact in different conditions. Thus, the statement clearly delineates the properties of these subatomic particles in a manner consistent with established scientific knowledge.
