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.

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.
