Atomic Structure

Front

Subatomic particles with a negative charge

Back

Electrons are subatomic particles that carry a negative charge and are found in the electron cloud surrounding the nucleus of an atom.

Front

Subatomic particles with a positive charge

Back

Protons are subatomic particles that carry a positive charge and are located in the nucleus of an atom.

Front

What is the nucleus of an atom made of?

Back

The nucleus of an atom is made of protons and neutrons.

Front

What part of the atom represents the proton in a diagram?

Back

In a typical atomic diagram, protons are often represented by a specific label or color, commonly denoted as 'c'.

Front

What is the smallest particle of an element that shows all the properties of that element?

Back

An atom is the smallest particle of an element that retains all the chemical properties of that element.

Front

What are neutrons?

Back

Neutrons are subatomic particles found in the nucleus of an atom that have no charge (neutral) and contribute to the atomic mass.

Front

What is the charge of a proton?

Back

A proton has a positive charge.

Front

What is the charge of a neutron?

Back

A neutron has no charge; it is neutral.

Front

What is the electron cloud?

Back

The electron cloud is the region around the nucleus of an atom where electrons are likely to be found.

Front

What is atomic mass?

Back

Atomic mass is the weighted average mass of an atom's isotopes, measured in atomic mass units (amu).
