Atomic Structure

Front

What is the relative weight of electrons?

Back

Electrons have a relative weight of approximately 1/1836, which is negligible compared to protons and neutrons.

Front

What does the atomic mass tell you?

Back

The atomic mass tells you the total number of subatomic particles (protons and neutrons) in the nucleus of an atom.

Front

What is formed when you change the amount of neutrons in an atom?

Back

An isotope is formed when the number of neutrons in an atom changes.

Front

What is the charge of electrons?

Back

Electrons are negatively charged particles.

Front

Does changing the number of neutrons affect an atom's mass?

Back

Yes, changing the number of neutrons changes an atom's mass.

Front

What are protons?

Back

Protons are positively charged subatomic particles found in the nucleus of an atom.

Front

What is the atomic number?

Back

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

Front

What is the mass number?

Back

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

Front

What are neutrons?

Back

Neutrons are neutral subatomic particles found in the nucleus of an atom.

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.
