Question

match the following descriptions with its corresponding subatomic particle. some may be used more than once, some may not be used at all protons neutrons electrons holds the nucleus together lives outside the nucleus equals the atomic # determines the element responsible for reactions/bonding

Explanation:

• Protons and neutrons are in the nucleus. Neutrons help hold the nucleus together via the strong - nuclear force.
• Electrons are outside the nucleus in electron - shells.
• The number of protons equals the atomic number and determines the element.
• Electrons are involved in chemical reactions and bonding.

Answer:

• Holds the nucleus together: Neutrons
• Lives outside the nucleus: Electrons
• Equals the atomic #: Protons
• Determines the element: Protons
• Responsible for reactions/bonding: Electrons
