Periodická tabulka - Obrazová encyklopedie chemických prvků – Jackson Tom (2022)

Discover the elements - the basic building blocks of matter that make up not only our world but the entire universe. These include gold, oxygen, phosphorus, and helium, among others. Today, we know a total of 118 elements. Many of them have unique, sometimes surprising chemical and physical properties. For example, gallium is a metal, yet it melts in your palm due to heat, and fluorine is a gas that can burn a hole in concrete! Elements are usually not found in their pure form. We find them combined with other elements in compounds. For instance, hydrogen and oxygen are found in water, sodium and chlorine form table salt, and carbon is part of millions of compounds, many of which make up our bodies. In this book, we will explore the periodic table of elements in detail, from actinium to zirconium. The elements are organized according to related properties. Scientists have gained a wealth of valuable information from this invaluable tool, and you will read the story of each element, accompanied by fascinating photographs - about how it was discovered, what properties it has, and how we can use it.
