Why do some metals float on water while others sink — and why do certain elements react so violently they seem to explode? In this video, we explore the extreme behavior of metals across the periodic table, from alkali metals reacting with water to materials that can withstand incredible temperatures. You’ll learn how density, reactivity, and atomic structure shape the properties we observe, and how early chemists like Robert Bunsen used clever chemical techniques to identify and separate elements. Whether it’s metals that refuse to melt, unexpected reactions, or the science behind classic laboratory demonstrations, this video breaks down the chemistry in a clear and engaging way.
