• protons

• Neutrons

• Electrons

• Shells

Subatomic particles that are neutral in charge

• Neutrons
• Protons
• Nucleus 
• Electrons

Where electrons are likely to be found as they travel around the nucleus

• Nucleus
• Electron Cloud
• Within a Proton
• Within a Neutron

What is one way Neutrons are different from electrons?

• they both are negative

• neutrons have no charge, while electrons have a negative charge

• Both are in the nucleus( center of atom)

• Electrons are inside nucleus and neutrons are outside the nucleus.
