What is the charge of a proton?

• Positively charged particle (+)

• Negatively charged particle (-)

• Neutrally charged particle (0)

Why is an electron important within the atom?

• I'ts important because it tells you the identity of the atom

• It's important becaue the atom repells other atoms.

• Important becuase is exerts a strong force to balance the atom.

• Important because it determines chemical reactivity

What is the charge of a neutron?

• Postively charged particle

• Negatively charged particle

• Neutrally charged particle

• Extra charged Particle

What is the charge of an electron?

• Postively charged particle

• Negatively charged particle

• Neutrally charged particle

• No charged

Select the correct answer that matches the correct mass with the subatomic particle.

• proton: 0amu, neutron: 1 amu, electron: 0amu

• proton: 1amu, neutron: 0amu, electron: 1amu

• proton: 1amu, neutron: 1 amu, electron: 0amu

• proton: +1 , neutron: 0 , electron: -1

The atomic number on the periodic table can tell us. Use period table https://ptable.com/#Properties

• # of electrons

• # of protons and the identitiy of the atom.

• # of neutrons

• # or protons and neutrons.
