1.4 Relative electrical charges of subatomic particles

• Protons have a positive electrical charge of +1
• The three main subatomic particles are protons, neutrons, and electrons
• Neutrons have no electrical charge


  True
• Protons have a positive electrical charge of +2

  False
• Arrange the subatomic particles in order of their electrical charge from most positive to most negative:

  1️⃣ Proton (+1)

  2️⃣ Neutron (0)

  3️⃣ Electron (-1)
• A neutron has an electrical charge of 0
• Electrons orbit the nucleus and carry a negative electrical charge.
• Match the subatomic particle with its relative electrical charge:

  Proton ↔️ +1

  Neutron ↔️ 0

  Electron ↔️ -1
• A neutron has a relative electrical charge of 0
• Subatomic particles are the building blocks of an atom
• There are three types of subatomic particles: protons, neutrons, and electrons.

  True
• Electrons have a negative electrical charge.


  True
