Which statement best describes the variables in a controlled experiment?
When can a theory be modified if a new type of technology allows for new observations that raise new questions?
Which is a process that involves collecting information and ideas that are supported by belief or opinion?
Which most likely is a causal relationship?
The electron cloud model is a modern theory about the structure of atoms that explains many of the atom’s behaviors. According to the model, scientists imagine an atom to have a large nucleus of matter in the center surrounded by tiny particles called electrons. These electrons fly so fast and unpredictably around the nucleus that just one electron can appear to be a cloud. However, individual electrons are far too small for a human to see or touch.
