The periodic table of elements

"A book of fun chemistry experiments has fallen into the wrong hands. Only Mel can use her knowledge of the periodic table to put an end to a maniacal madman's evil schemes. The periodic table helps us quickly understand the 118 elements, those tiny substances that make up everything in the world. By using the periodic table, we can recognize how these building blocks behave, find trends and patterns in the universe, and make predictions about elements that haven't been discovered yet"--Provided by publisher.
