Chapter 4, Problem 19b
Identify each of the following as describing either a proton, a neutron, or an electron:
a. has the smallest mass
Verified step by step guidance1
Step 1: Begin by recalling the relative masses of subatomic particles. A proton and a neutron have similar masses, approximately 1 atomic mass unit (amu), while an electron has a much smaller mass, approximately 1/1836 of the mass of a proton.
Step 2: Compare the masses of the three particles. Since the electron's mass is significantly smaller than that of a proton or neutron, it is the particle with the smallest mass.
Step 3: Understand the significance of this property. The small mass of the electron allows it to move rapidly around the nucleus, contributing to the atom's overall structure and chemical behavior.
Step 4: Confirm that the correct identification for the particle with the smallest mass is the electron.
Step 5: Review the concept of subatomic particles and their properties to reinforce understanding of their roles in atomic structure.

Key Concepts
Here are the essential concepts you must grasp in order to answer the question correctly.
Proton
A proton is a positively charged subatomic particle found in the nucleus of an atom. It has a relative mass of approximately 1 atomic mass unit (amu) and plays a crucial role in determining the atomic number of an element, which defines its identity.

Isotopes
Neutron
A neutron is a neutral subatomic particle also located in the nucleus of an atom. It has a mass similar to that of a proton, approximately 1 amu, and contributes to the atomic mass of an element, influencing its stability and isotopic composition.

Electron
An electron is a negatively charged subatomic particle that orbits the nucleus of an atom. It has a significantly smaller mass than protons and neutrons, approximately 1/1836 of an amu, and is essential for chemical bonding and the formation of molecules.
