1.4.1 Charges and masses of protons, neutrons, and electrons

• What is the charge of a neutron?

  0
• Why is the equality of protons and electrons important in an atom?

  It ensures a balanced electrical charge
• What is the charge of neutrons?

  Neutral (no charge)
• Where are protons located in an atom?

  In the nucleus
• In a neutral atom, what is the relationship between protons and electrons?

  The number of protons equals the number of electrons
• Where are neutrons found in an atom?

  In the nucleus
• Where do electrons orbit in an atom?

  Around the nucleus
• How do protons, neutrons, and electrons relate to the structure of an atom?

  • Protons and neutrons form the nucleus (sun).
  • Electrons orbit around the nucleus (planets).
  • Opposite charges keep the atom balanced.
• What role do electrons play in chemical bonding?

  They interact with other atoms to form molecules
• What is the mass of a proton relative to itself?

  1
• Where do neutrons reside in an atom?

  In the nucleus
• What are subatomic particles?

  Smaller parts that make up atoms
• How do hydrogen and oxygen bond in water?

  Hydrogen shares an electron with oxygen
• What happens if the numbers of protons and electrons are unequal?

  The atom becomes an ion with a net charge
• What charge does an ion carry?

  A net positive or negative charge
• What is the significance of electrical charges of subatomic particles?

  They are crucial for atom stability and chemical reactions
• What is the charge of a proton?

  +1
• What do electrons participate in within an atom?

  Chemical bonding
• What is the role of neutrons in an atom?

  They contribute to the atom's mass
• How do protons and electrons interact in a neutral atom?

  Positive protons balance negative electrons
• What charge do electrons have?

  Negatively charged
• What determines an atom's chemical properties?

  The number and arrangement of electrons
• How many protons and electrons does hydrogen have?

  One proton and one electron
• What is the mass of an electron relative to a proton?


  0
• What defines the element of an atom?

  The number of protons
• How do protons and electrons differ in their contributions to an atom?

  Protons define the element; electrons determine chemical properties
• What is created when electron charges are used in bonding?

  A stable bond between atoms
• What are the main types of subatomic particles?

  • Protons
  • Neutrons
  • Electrons
• What is the charge of an electron?

  -1
• What charge do protons have?

  Positively charged
• How can you visualize the structure of an atom?

  • Nucleus: small, dense group of protons and neutrons
  • Electrons: spin around the nucleus like planets
• What is the mass of a neutron relative to a proton?
