  2. 1. What type of bonds are shown in this diagram?

    A diagram shows a number of circles, each marked with a ‘+,’ surrounded by a number of smaller, blue balls. Arrows seem to indicate that the blue balls are moving around and between the circles. A key at the bottom of the illustration shows the circles with the plus signs are metal ions and the blue balls are electrons.

    What types of bonds are shown in this diagram?

    A diagram shows a number of structures that consist of two white balls connected by white rods to a larger, red ball. Waves of green lines run from each white ball to the nearest red ball other than its own.

    Which statement best describes the types of bonds shown in the diagram?

    A diagram, labeled ‘hydrogen chloride molecule,’ shows two atoms. The one on the right has ‘CL’ in the center and three rings around it. The inner ring has two grey balls on it, the middle and outer rings have eight. One of the eight on the outer ring also sits on the single ring that surrounds the atom labeled ‘H’ on the left.

  3. 1. PROBABLY this is a covalent bond if I've interpreted the scenario correctly.
    2. I would go with b although technically ionic bonds are formed between IONS (not atoms) that have opposite charges.
    3. I'm nor able to interpret the diagram.
    4. Clearly a is the answer. Good description.
    5. Covalent bonds, in general, are the strongest.
    Note: I don't understand why you need to type all of the possible answer choices EXCEPT the final one TWO times. It makes reading them difficult to separate and decide how to answer. I think in the past you have answered that the "program" goes that. Frankly, I don't believe that. If it IS true I would find a new program.
