Subatomic particles

The video tutorial discusses subatomic particles, starting with neutrons, protons, and electrons, which were initially thought to be the only subatomic particles. It then introduces additional particles discovered later, such as neutrinos, antielectrons, antiprotons, antineutrons, muons, and bosons.

Which of the following are considered basic subatomic particles?

• Quarks, leptons, and bosons

• Neutrons, protons, and electrons

• Atoms, molecules, and ions

• Neutrinos, muons, and bosons

How do the masses of neutrons and protons compare to that of electrons?

• Neutrons are heavier than protons and electrons

• Electrons are heavier than both neutrons and protons

• Neutrons and protons have roughly the same mass, which is heavier than electrons

• Neutrons and protons are much lighter than electrons

In the early 20th century, which particles were believed to be the only subatomic particles?

• Quarks, leptons, and bosons

• Neutrinos, antielectrons, and muons

• Atoms, molecules, and ions

• Neutrons, protons, and electrons

Which of the following is NOT a subatomic particle discovered after the early 20th century?

• Neutrinos

• Antielectrons

• Atoms

• Muons

Which of these particles is considered an antiparticle?

• Neutron

• Electron

• Antiproton

• Proton
