A teacher is giving a demonstration at the front of the classroom. The students are being asked to identify which group an element would belong to based on its properties. A bowl of water sits on the lab bench, along with a butter knife and the unidentified element. The teacher buts the element into very small pieces using a butter knife. She shows the class that the element is sold and has a dull finish. She drops the small piece of the element into the bowl of water where it briefly sizzles, and a flash of light appears. -Based on the demonstration, what family (group) do you think this element belongs in? Justify your answer using evidence from the text.

The correct answer is "atomic weight".
