Answer:
Classify each statement as an observation, a law, or a theory. a. Chlorine is a highly reactive gas. b. If elements are listed in order of increasing mass of their atoms, their chemical reactivity follows a repeating pattern. c. Neon is an inert (or nonreactive) gas. d. The reactivity of elements depends on the arrangement of their electrons.in order to classify each of these as an observation, a law or a theory. We need to recall the definition of an observation of law in a theory and observation is usually a one time occurrence associated with one particular phenomenon. We're a law similar to, an observation describes what occurs for multiple phenomena or um describes what occurs for multiple things. It is far more general, but a law similar to an observation is just describing what is happening. A theory different from both of them, attempts to explain what is happening. So the first statement chlorine is a highly reactive gas. That would simply be an observation. It's an observation because it is simply describing what is occurring with chlorine B states if elements are listed in order of increasing mass of their atoms, their chemical reactivity follows a repeating pattern. This would be a law because now we are talking about what is occurring with many different elements. We are, what we are describing what occurs in nature C states neon is an inert or non reactive gas. This would just be an observation as it is describing the way neon behaves. And the last one is the reactivity of elements depends on the arrangement of their electrons. This one seems a little bit more confusing. It is describing what occurs with many different elements. It is describing how reactivity is associated with arrangement of electrons. So it is attempting to explain reactivity as it attempts to explain something. This would be a theory
