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

All atoms are nuetral means

• Neutrons = protons

• Protons = electrons

• Neutrons = electrons

• None of the above
