Why it is important to understand how the chemicals in the periodic table combine.

The periodic table of elements is useful for modern students and scientists because it helps predict the types of chemical reactions that a particular element is likely to participate in. Rather than memorizing facts and figures for each element, students and scientists need only glance at the table to learn much about the reactivity of an element, whether it is likely to conduct electricity, whether it is hard or soft, and many other characteristics. When chemicals in the table combine they make compounds. Eventually many compounds form an object like an ocean or a living being. Combining chemicals in the table of elements can make new things like a vaccine or a cure to a disease. They may make some super food or a powerful chemical.
