Which two subatomic particles make up the nucleus of an atom?
The two subatomic particles that make up the nucleus of an atom are protons and neutrons.
The two subatomic particles that make up the nucleus of an atom are protons and neutrons.
To confirm this, you can follow these steps:
Step 1: Understand the structure of an atom.
An atom consists of a central nucleus surrounded by one or more electrons. The nucleus contains subatomic particles known as protons and neutrons. Electrons, which have a negative charge, orbit around the nucleus in energy levels.
Step 2: Identify the roles of protons and neutrons.
Protons have a positive charge and contribute to the overall positive charge of the nucleus. Neutrons, on the other hand, have no charge and add to the mass of the nucleus. Both protons and neutrons are located within the nucleus.
Step 3: Review reliable scientific sources.
Consulting credible scientific sources such as textbooks, scientific journals, or educational websites can provide further evidence about the composition of the nucleus.
By following these steps, you can determine that the nucleus of an atom is composed of protons (with a positive charge) and neutrons (with no charge).
