Atomic Number, Mass Number, and Net Charge by Tyler Dewitt

According to the video, what is the atomic number?

• The number of neutrons in an atom

• The number of protons in an atom

• The number of electrons in an atom

• The number of protons plus neutrons in an atom

How is the atomic number abbreviated?

• P

• Z

• A

• N

What is the mass number?

• The number of protons in an atom

• The number of neutrons in an atom

• The number of electrons in an atom

• The number of protons plus neutrons in an atom

How is the mass number calculated?

• By subtracting the number of protons from the number of neutrons

• By adding the number of protons and neutrons

• By multiplying the number of protons by the number of neutrons

• By dividing the number of protons by the number of neutrons

What is net charge?

• The balance between the number of neutrons and protons in an atom

• The difference between the number of electrons and protons in an atom

• The overall mass of an atom

• The ability of an atom to form bonds with other atoms

How do protons and electrons balance each other out in an atom?

• Protons have a positive charge and electrons have a negative charge

• Protons have a negative charge and electrons have a positive charge

• Protons and electrons have the same charge

• Protons and electrons have no charge

What is an ion?

• An atom with a net charge

• An atom with no net charge

• A type of subatomic particle

• A unit of measurement for atomic mass
