the average number of neutrons
if you didnt have

Explanation:

• Protons have a positive charge, are located in the nucleus, and determine an atom's identity.
• The mass of an atom/element is due to protons and neutrons.
• Neutrons have no charge (neutral), are in the nucleus, and found by subtracting atomic number from atomic mass.
• Atomic mass is usually a whole number and equal to protons plus average neutrons.

Answer:

• proton: positive, nucleus, atom, identity
• mass: protons, neutrons
• neutron: neutral, subtracting
• atomic mass: whole number, plus
