Atoms Structure

Front

What is the mass number of an atom, and how is it calculated?

Back

The mass number of an atom is the total number of protons and neutrons in its nucleus. It is calculated by adding the number of protons (atomic number) to the number of neutrons.

Front

How many neutrons are in an atom with 36 protons and a mass number of 84?

Back

48 neutrons.

Front

What particles are found in the nucleus of an atom?

Back

Protons and neutrons.

Front

What are the three fundamental particles that make up an atom?

Back

Neutrons, electrons, and protons.

Front

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

Back

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

Front

What is the charge of protons and where are they located?

Back

Protons have a positive charge and are located in the nucleus of an atom.

Front

What is the charge of neutrons and where are they located?

Back

Neutrons have no charge (neutral) and are located in the nucleus of an atom.

Front

What is the significance of the atomic number of an element?

Back

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

Front

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

Back

Negatively charged particles (electrons).

Front

How do the number of protons and electrons relate in a neutral atom?

Back

In a neutral atom, the number of protons equals the number of electrons.
