HW 1.5 Atomic Structure

Subatomic particles with a negative charge

• Electrons

• Neutrons

• Protons

• Quarks

Subatomic particles that are neutral in charge

• Neutrons
• Protons
• Nucleus 
• Electrons

Subatomic particles with a positive charge

• neutrons
• atomic mass
• protons
• isotopes

The nucleus of an atom is made of

• electrons and protons
• electrons and neutrons
• protons and neutrons
• empty space

The mass of this particle is so small that it is not counted.

• proton
• electron
• neutron
• quark

The term "neutral" means

• having only a little bit of charge
• having a positive charge
• having a negative charge
• having no charge at all

Where is the nucleus located in an atom?

• Near the electron shells/levels
• Near the center of an atom

Where are the Electrons found in the structure of an atom?

• In the nucleus
• In spaces around the nucleus
