4.1.1 Subatomic Particles

Cards (29)

  • Subatomic particles are the fundamental particles that make up an atom
  • Match the subatomic particle with its location and charge:
    Protons ↔️ In the nucleus, positive
    Neutrons ↔️ In the nucleus, neutral
    Electrons ↔️ Orbiting the nucleus, negative
  • Electrons orbit the nucleus in specific shells
  • What makes up the nucleus of an atom?
    Protons and neutrons
  • Order the subatomic particles based on their mass from heaviest to lightest:
    1️⃣ Protons
    2️⃣ Neutrons
    3️⃣ Electrons
  • Protons and neutrons have approximately equal masses, while electrons are significantly lighter.
  • Where are protons located within an atom?
    In the nucleus
  • Neutrons are located in the nucleus of an atom.
  • Electrons orbit the nucleus in specific shells or energy levels.
  • The nucleus of an atom is composed of protons and neutrons.
  • What is the approximate mass of a proton in atomic mass units (amu)?
    1 amu
  • Electrons are significantly lighter than protons and neutrons.
  • What is the mass of a neutron in atomic mass units (amu)?
    1 amu
  • The mass of an electron is approximately 1/1836 amu.
  • Protons have a positive charge, neutrons have a neutral charge, and electrons have a negative charge.
  • What type of charge do protons carry?
    Positive (+)
  • Neutrons are electrically neutral.
  • What type of charge do electrons carry?
    Negative (-)
  • Subatomic particles are the fundamental components of an atom.
  • What is the approximate mass of an electron in atomic mass units (amu)?
    1/1836 amu
  • Protons have a positive charge and a mass of approximately 1 amu.
  • Protons and neutrons make up the nucleus of an atom.
  • Protons and neutrons have approximately equal masses.
  • Arrange the subatomic particles by their mass from heaviest to lightest:
    1️⃣ Protons
    2️⃣ Neutrons
    3️⃣ Electrons
  • The mass of an electron is about 1/1836 amu.
  • The difference in charge between subatomic particles is fundamental to atomic structure.
  • Match the subatomic particle with its role in determining atomic properties:
    Protons ↔️ Atomic number
    Neutrons ↔️ Atomic mass
    Electrons ↔️ Chemical properties
  • Which subatomic particle determines the atomic number of an element?
    Protons
  • Neutrons determine the atomic mass and isotopes of an atom.
