Here are the answers for the questions you provided:

Question 23: The most electronegative element is:

  • a. Fluorine

Question 24: Match the part of an atom to its description:

  1. Proton: b. positively charged particle
  2. Neutron: a. neutral particle
  3. Electron: c. negatively charged particle
  4. Nucleus: d. the area of the atom where positive particles and neutral particles are found
  5. Electron cloud: e. the area of the atom where negatively charged particles are found

Question 25: Match the group to the type of ions they form:

  1. Group 1A: a. +1
  2. Group 2A: e. +2
  3. Group 3A: c. +3
  4. Group 4A: b. +4/-4
  5. Group 5A: g. -3
  6. Group 6A: f. -2
  7. Group 7A: d. -1
  8. Group 8A: h. 0

Question 26: Match the part of the diagram to its correct label: (This is not fully possible without the diagram, but here are the potential assignments based on standard atomic structure.)

  1. W: b. Proton (common label for protons could be W)
  2. X: a. Neutron (common label for neutrons could be X)
  3. Y: d. Electron (common label for electrons could be Y)
  4. Z: c. Nucleus (common label for nucleus could be Z)

Question 27: The chloride ion has a -1 charge because:

  • b. Chlorine atoms gain an electron.

Question 28: The atomic number and mass number convey:

  • c. The element has 12 protons and has 28 neutrons. (Mass number = Protons + Neutrons, so 40 - 12 = 28 neutrons)

Question 29: In all elements in a group, the thing that is the same is the:

  • a. Number of electrons in the valence shell.

Question 30: (This question requires personal responses based on resources you reviewed.)

Your answer should include:

  1. Name of Resource 1: (e.g., "Atomic Structure Video")

    • What you learned from it: (e.g., "I learned about the basic components of an atom, including protons, neutrons, and electrons.")

  2. Name of Resource 2: (e.g., "Periodic Table Review Sheet")

    • What you learned from it: (e.g., "The review sheet helped me understand how to determine the number of neutrons based on mass number and atomic number.")

Question 31: When you have completed a Sample Work with a grade of 70% or higher, you should:

  • d. Submit a screenshot of the score and submit it to the dropbox in Connexus.

Question 32: You can find guided notes to help you go through the lessons in Connexus in:

  • c. Connexus.

Question 33: If you get a month behind, you won't lose any points for your work.

  • b. False. (Typically, you may lose points for being behind on assignments.)
