The periodic table as you’ve never seen it before—starring the elements that power our bodies and our way of life
Some elements get all the attention: glittering gold, radioactive uranium—materials we call “precious” because they are so rare. But what could be more precious than the building blocks of life—from the oxygen in our air to the carbon in all living things?
In The Elements We Live By, physicist and award-winning author Anja Røyne reminds us that we’d be lost without the quiet heroes of the periodic table. Our bodies need phosphorous to hold our DNA together, potassium to power our optic nerves, and many more elements—in just the right amounts—to function. Other fundamental elements keep our technology (and society) running: Our phones contain arsenic, boron, and gallium to control signals and store information; indium and tin for the touch screen; and lithium for the battery.
Everything is made of elements—every galaxy, star, and planet—from the iron in Earth’s core to the silicon in its sand. But that doesn’t mean the elements we rely on will never run out; for example, about half of the lithium we need is extracted from rocks in Australia, and the other half is from saltwater in Argentina and Chile. As Røyne travels the world to find where these elements exist (some in ever-shrinking amounts), she shows how vitally urgent it is for us to protect them—the elements of our very existence.

      Gr 9 Up-Beginning with the Big Bang and the creation of all matter, this title goes on to explain various chemical elements essential to modern life. Some serve necessary biological functions within the human body. Others are integral to technology and industry. The author explains how procuring the various elements affects the environment, predictions for when supplies may be exhausted, and even possible space mining or colonization in the future. Not just a discussion of basic chemistry, this is a volume that looks at the human impact on the planet and what we can learn from nature. All references are derived from blog posts or articles easily accessible to readers, but the sources they are based on have been checked for accuracy and authenticity by the author. VERDICT Useful for science or sociology courses that address the various impacts of natural resource development or for popular science readers.
