  False
• Neutrons carry a positive charge.

  False
• Electrons have a mass of 1 atomic mass unit (amu).

  False
• What is the charge of a proton?

  +1
• What is the charge of an electron?

  -1
• Order the subatomic particles from heaviest to lightest:

  1️⃣ Proton

  2️⃣ Neutron

  3️⃣ Electron
• What are the three main types of subatomic particles?

  Protons, neutrons, electrons
• What is the charge of a neutron?

  0
• Protons and neutrons reside in the nucleus
• What is the charge of a proton?

  +1
• The mass of an electron is almost 0
• Protons and neutrons form the dense central core of an atom called the nucleus.


  True
• Electrons determine the chemical properties of atoms.

  True
• Protons and neutrons are located in the nucleus
• Electrons have a positive charge.

  False
• Electrons have a significantly smaller mass compared to protons and neutrons.


  True
• What is the charge of a proton?

  Positive (+1)
• Where in the atom is a proton located?

  Nucleus
• Neutrons have no electrical charge.


  True
• Electrons orbit the nucleus
• What is the approximate mass of an electron in atomic mass units (amu)?

  Almost 0 amu
• Match the subatomic particle with its properties:

  Proton ↔️ Positive charge, in nucleus

  Neutron ↔️ Neutral charge, in nucleus

  Electron ↔️ Negative charge, orbits nucleus
• What is the charge of a neutron?

  0
• Protons and neutrons reside in the dense central core of the atom known as the nucleus
• Electrons have almost 0 atomic mass units (amu).


  True
• What type of charge does a proton have?

  Positive
• What type of charge does an electron have?

  Negative
• Neutrons have a neutral charge, which means their charge is 0
• Match the term with its definition:

  Isotopes ↔️ Atoms with the same number of protons but different neutrons

  Atomic number ↔️ Number of protons in an atom

  Mass number ↔️ Total number of protons and neutrons in an atom
