2. Florine is a toxic, reactive gas. Which representation (structural formula, electron dot structure, or three-dimensional model) would you use to explain why fluorine so reactive? Why?

Use the electron dot structure to show that Fluorine has an electronic configuration of (2,7).

It only requires one more electron to obtain the stable electronic configuration of a noble gas, which is an octet electronic configuration. Hence, it reacts readily with other elements.
