Explain why chlorine is a gas while iodine is a solid yet both are halogens. Select one: a. Both iodine and chlorine differ in strength of metallic bonds b. Chlorine has strong inter molecular forces than iodine c. Iodine molecules are large with strong inter molecular forces than chlorine

c. Iodine molecules are large with strong inter molecular forces than chlorine

Explanation:

Even though they are divalent molecules, iodine has more electrons per molecule than chlorine which means that iodine has more contact surfaces for intermolecular forces to act on between individual molecules.

thats a little if u want the answer just look it up on google thats what i do haha : )

qualitative observation deals with data that can be observed with our senses: sight, smell, touch, taste, and hearing. they do not involve measurements or numbers. for instance, colors, shapes, and textures of objects are all qualitative observations.
