Front

What are protons?

Back

Protons are positively charged particles found in the nucleus of an atom.

Front

What are neutrons?

Back

Neutrons are neutral particles found in the nucleus of an atom, with no charge.

Front

What are electrons?

Back

Electrons are negatively charged particles that orbit the nucleus of an atom.

Front

What is an energy level in an atom?

Back

Energy levels are the regions around the nucleus where electrons are likely to be found.

Front

How many protons does an atom with 3 electrons have?

Back

An atom with 3 electrons has 3 protons, as the number of protons equals the number of electrons in a neutral atom.

Front

What is the charge of a proton?

Back

The charge of a proton is +1.

Front

What is the charge of an electron?

Back

The charge of an electron is -1.

Front

What is the charge of a neutron?

Back

Neutrons have no charge (neutral).

Front

What is the atomic number of an element?

Back

The atomic number is the number of protons in the nucleus of an atom, which determines the element's identity.
