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

Back

Neutrons = Mass Number - Atomic Number.

Front

Which subatomic particle has the most mass?

Back

Protons and Neutrons have similar mass, but in terms of charge, Protons are positively charged.

Front

What is the largest particle accelerator in the world?

Back

The Large Hadron Collider (LHC) is the world's largest and most powerful particle accelerator.

Front

What type of charge do Protons have?

Back

Protons have a positive charge.

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 charge do Neutrons have?

Back

Neutrons have no charge; they are neutral.

Front

What is the role of Electrons in an atom?

Back

Electrons are negatively charged particles that orbit the nucleus and are involved in chemical bonding.

Front

What is an Isotope?

Back

Isotopes are variants of a particular chemical element that have the same number of protons but different numbers of neutrons.
