Structure of the atom

Front

What is the basic structure of an atom?

Back

An atom consists of a nucleus containing protons and neutrons, surrounded by electrons in orbitals.

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, contributing to its mass.

Front

What are electrons?

Back

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

Front

What is atomic mass?

Back

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

Front

How do you calculate the number of neutrons in an atom?

Back

Number of neutrons = Atomic mass - Number of protons.

Front

What is an ion?

Back

An ion is an atom that has gained or lost one or more electrons, resulting in a net charge.

Front

What is a neutral atom?

Back

A neutral atom has an equal number of protons and electrons, resulting in no overall charge.

Front

What are isotopes?

Back

Isotopes are atoms of the same element that have different numbers of neutrons.

Front

What is the charge of a neutron?

Back

Neutrons have no charge; they are neutral.
