Multiple Choice

What is the charge of a proton?

• Positively charged particle (+)

• Neutrally charged particle (0)

• Negatively charged particle (-)

Multiple Choice

Why is the Proton important within the atom?

• It's important because it tells you the identity of the atom

• It's important because the atom repels other atoms.

• Important because it determines chemical reactivity

Multiple Choice

Why is an electron important within the atom?

• Important because it determines chemical reactivity

• It's important because it tells you the identity of the atom

• It's important because the atom repels other atoms.

Multiple Choice

What is the charge of an electron?

• Neutrally charged particle

• Positively charged particle

• Negatively charged particle

Multiple Choice

Why is a neutron important within the atom?

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

• Important because it determines chemical reactivity

• It's important because the atom repels other atoms.

Multiple Choice
