Here's why:
* Elements are the building blocks of matter: The periodic table lists all known elements.
* Liquids are states of matter: A substance can be a liquid, solid, or gas depending on its temperature and pressure.
Two elements are liquids at room temperature:
1. Bromine (Br): A reddish-brown liquid with a strong, unpleasant odor.
2. Mercury (Hg): A silvery-white liquid, also known as quicksilver.
Important Note: Many other elements can become liquids at higher temperatures!
