Atoms Structure

Front

What determines the charge of an atom?

Back

The charge of an atom is determined by the number of protons and electrons.

Front

Where are electrons located in an atom and what is their charge?

Back

Electrons are located outside the nucleus and have a negative charge.

Front

Which subatomic particles contribute most to the mass of an atom?

Back

Protons and neutrons contribute most to the mass of an atom.

Front

What type of particles are found in the cloud surrounding an atom's nucleus?

Back

Negatively charged particles (electrons) are found in the cloud surrounding the atom's nucleus.

Front

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

Back

The number of neutrons can be calculated by subtracting the number of protons from the mass number.

Front

What is the mass number of an atom?

Back

The mass number of an atom is the total number of protons and neutrons in its nucleus.

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 significance of the atomic number?

Back

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

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.
