Atomic Structure/Bohr Models

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.

Front

What are the three main subatomic particles in an atom?

Back

The three main subatomic particles are protons, neutrons, and electrons.

Front

What charge do protons carry?

Back

Protons carry a positive charge.

Front

What charge do neutrons carry?

Back

Neutrons carry no charge (they are neutral).

Front

What charge do electrons carry?

Back

Electrons carry a negative charge.

Front

Where are protons and neutrons located in an atom?

Back

Protons and neutrons are located in the nucleus of an atom.

Front

What is the mass of an electron compared to protons and neutrons?

Back

Electrons have a much smaller mass compared to protons and neutrons.

Front

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

Back

The number of neutrons can be determined by subtracting the atomic number from the atomic mass.

Front

What is the significance of the Bohr model in atomic structure?

Back

The Bohr model describes the arrangement of electrons in orbits around the nucleus and explains quantized energy levels.

Front

What is an ion?

Back

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