Textbook Question

What are the three subatomic particles in atoms?

Verified step by step guidance

Understand that atoms are the basic building blocks of matter and consist of smaller components called subatomic particles.

Learn that there are three main types of subatomic particles: protons, neutrons, and electrons.

Protons are positively charged particles found in the nucleus of an atom. They determine the atomic number and identity of the element.

Neutrons are neutral particles (no charge) also located in the nucleus. They contribute to the atomic mass and help stabilize the nucleus.

Electrons are negatively charged particles that orbit the nucleus in energy levels or shells. They are involved in chemical bonding and reactions.

Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

Subatomic Particles

Subatomic particles are the fundamental constituents of atoms, which include protons, neutrons, and electrons. These particles are essential for understanding the structure and behavior of matter at the atomic level.

Protons

Protons are positively charged particles found in the nucleus of an atom. They determine the atomic number of an element, which defines the element's identity and its position in the periodic table.

Electrons

Electrons are negatively charged particles that orbit the nucleus of an atom in various energy levels. Their arrangement and interactions with other atoms are crucial for chemical bonding and reactions.
