The Nucleus

Front

What role do neutrons play in the nucleus?

Back

Neutrons serve as a buffer between protons, helping to stabilize the nucleus by reducing the repulsive forces between positively charged protons.

Front

What is the strongest fundamental force that holds nuclei together?

Back

The strong nuclear force is the strongest of the four fundamental forces of physics and is responsible for holding the nucleus together.

Front

What is the mass and charge of a neutron?

Back

A neutron is heavy and neutral, meaning it has no electric charge.

Front

What is Brownian motion?

Back

Brownian motion is the random motion of particles suspended in a fluid, named after botanist Robert Brown.

Front

What do atoms of the same element have in common?

Back

Atoms of the same element have the same number of protons in their nuclei.

Front

What is the charge of protons?

Back

Protons have a positive charge.

Front

What is the charge of electrons?

Back

Electrons have a negative charge.

Front

What is the relationship between protons and atomic number?

Back

The atomic number of an element is defined by the number of protons in its nucleus.

Front

What is the difference between isotopes of an element?

Back

Isotopes of an element have the same number of protons but different numbers of neutrons.

Front

What is the significance of the strong nuclear force?

Back

The strong nuclear force is crucial for the stability of atomic nuclei, preventing them from collapsing due to the repulsion between protons.
