"When atoms bond chemically into a unit, theyre called a molecule. A common example is a water molecule: two atoms of the element hydrogen and one atom of the element oxygen. These elements have particular properties that allow them to react to create the water that is vital for life on Earth. This valuable volume takes the mystery out of molecules such as this, illuminating key chemistry concepts using real-life examples, labeled diagrams, and fact boxes to help readers build on their knowledge. Budding scientists will appreciate the thought-provoking information throughout the book, which emphasizes curricular content"--.
