Questions & Step-by-Step Solutions
Which of the following statements about electrons is true?
Correct Answer: Electrons have a negligible mass compared to protons and neutrons.
Step 1: Understand what electrons are. Electrons are tiny particles that are part of atoms.
Step 2: Know that atoms are made up of three main particles: protons, neutrons, and electrons.
Step 3: Learn that protons and neutrons are found in the nucleus (center) of the atom, while electrons orbit around the nucleus.
Step 4: Compare the mass of electrons to protons and neutrons. Protons and neutrons are much heavier than electrons.
Step 5: Recognize that the mass of an electron is so small that it is often considered negligible (not significant) when compared to protons and neutrons.
