Subatomic Particles

Front

What is the nucleus?

Back

The nucleus is the central part of an atom, containing protons and neutrons. It is positively charged and holds most of the atom's mass.

Front

What is a neutron?

Back

A neutron is a subatomic particle found in the nucleus of an atom. It has no charge (neutral) and contributes to the mass of the atom.

Front

What is a proton?

Back

A proton is a positively charged subatomic particle located in the nucleus of an atom. The number of protons determines the element's identity.

Front

What is an electron?

Back

An electron is a negatively charged subatomic particle that orbits the nucleus of an atom. It has a very small mass compared to protons and neutrons.

Front

What is the charge of a neutron?

Back

A neutron has no charge; it is neutral.

Front

What is the charge of a proton?

Back

A proton has a positive charge.

Front

What is the charge of an electron?

Back

An electron has a negative charge.

Front

Which subatomic particle has the least mass?

Back

Electrons have the least mass compared to protons and neutrons.

Front

What does the yellow circle represent in atomic diagrams?

Back

The yellow circle typically represents an electron in atomic diagrams.

Front

How do protons and electrons interact?

Back

Protons and electrons attract each other due to their opposite charges, which helps to keep electrons in orbit around the nucleus.
