Four Elements and the Periodic Table [PDF ebook] 

This book on the four elements and the periodic table shows the scientific method at work and proves and disproves the subjects at hand. It explores a branch of modern science or a major scientific milestone, comparing and contrasting it with an older idea that has been proved wrong or fails to meet the strict and studied standards of science. A robust index, glossary, science content, and bibliography accompanies the descriptive and concise text while the further reading section inspires future research and deeper thought.
