Protons, Electrons, and Neutrons: Part 1

Front

What is a proton?

Back

A proton is a positively charged subatomic particle found in the nucleus of an atom. It determines the atomic number of an element.

Front

What is an electron?

Back

An electron is a negatively charged subatomic particle that orbits the nucleus of an atom. It plays a key role in chemical bonding.

Front

What is a neutron?

Back

A neutron is a neutral subatomic particle found in the nucleus of an atom. It contributes to the mass of the atom but does not affect its charge.

How many protons does Barium (Ba) have?

Back

Barium has 56 protons.

Front

How many protons does Gallium (Ga) have?

Back

Gallium has 31 protons.

Front

How many electrons does Manganese (Mn) have?

Back

Manganese has 25 electrons.

Front

How many neutrons are in Mercury (Hg)?

Back

Mercury has 121 neutrons.

Front

How many protons are in Boron (B)?

Back

Boron has 5 protons.

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 is the relationship between protons and electrons in a neutral atom?

Back

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