Aprašymas

Liquid, shiny, dangerous Mercury has the distinction of being the only metal that is liquid at room temperature. Because of this trait, mercury is used in thermometers, scientific instruments, florescent lights, and many other devices. In this book, students will learn about mercury's unique properties as an element. They will also learn how mercury is mined and extracted, and how this element, though useful, is also very dangerous, to both the environment and animals. This book contains relevant resources students can use to continue their exploration of mercury and other elements.
