Question

You are a chemist working in your laboratory. In your storage closet you have a cabinet that holds only samples of pure elements, no compounds. While looking for a sample of lithium (Li), you notice that the label on one bottle has worn off. The room is at normal temperature. The contents of the bottle are liquid and do not look metallic. What element should you relabel the bottle as?

Answer 1

The element that should be relabeled on the bottle is sodium (Na).

Step-by-step explanation:

The element that should be relabeled on the bottle is sodium (Na).

The question mentions that the contents of the bottle are liquid and do not look metallic. Lithium (Li) is a solid metal at room temperature and is not liquid, so it is not the correct element. However, sodium (Na) is a a shiny, soft, and highly reactive metal that exists as a liquid at room temperature. It is part of the alkali metals group, which includes lithium, sodium, potassium, rubidium, cesium, and francium.
