Which of the following statements is NOT true about atoms?

• Electrons are negatively charged and are found in the electron cloud outside of the nucleus.

• Protons and neutrons are found in the nucleus.

• Protons have no charge.

• Neutrons are neutral in charge and are the same mass as protons.

• The number of protons is equal to the number of electrons in a neutral atom.

Select the statement that is NOT true.

• An element is a substance that is made entirely from one type of atom.

• For example, the element hydrogen is made from atoms containing a single proton and a single electron.

• If you change the number of neutrons an atom has, you change the type of element it is.

• All the above are true.
