• They do not have any electrical charge.

• They are found in the nucleus of the atom.

• They both spin around the nucleus of an atom.

What is a difference between protons and neutrons?

• Protons have a positive charge, while neutrons have no charge.

• Protons have no charge, while neutrons have a positive charge.

• Protons are found inside the nucleus, while neutrons spin around it.

• Protons spin around the nucleus, while protons are found inside it.

What is true about electrons?

What do atoms need in order to be most stable?

• They need to have no overall charge.

• They need to have the same number of protons as neutrons.

• They need to have a large number of electrons.

• All of the above

What are isotopes?

• Something that has two or more different types of atoms in it

• Substances made up of only one type of atom

• Atoms with the same number of protons but a different number of neutrons

• Elements that have more electrons than protons
