09 Polar Molecules

Why are some molecules polar, others not? Can this be seen in the molecular structure? Original: "Wolfgang Dukorn" Original: German. All translations in this video have been done by the alugha AI.

08 Naming of Molecules

From the molecular formula to the molecule name. What is carbon tetrachloride? Can you infer the molecular formula from the name? Original: "Wolfgang Dukorn" Original: German. All translations in this video have been done by the alugha AI.

08 The Electron Pair Bond - Molecules

Molecules are compounds of non-metal atoms. But how does the bond come about? They cannot give up or absorb electrons completely, because both partners want to have more. Using the fluorine molecule as an example, the electron pair bond is explained with the help of the energy level diagram. Origin

08 Ion formation

Rutherford's atomic model can already explain a simple formation of charged particles (ions). The PSE can help us detect whether an atom absorbs or releases electrons. Original: "Wolfgang Dukorn" Original: German. All translations in this video have been done by the alugha AI.

The Formation of Stars | NASA Planetary Sciences

Discover how the James Webb Space Telescope will help us better understand solar system formation in this video from NASA. Images from the Hubble Space Telescope show star-forming regions within the Eagle nebula: visible light images show vast clouds of gas and dust, and infrared images provide a gl

08 Reaction Equations Molecules and Salts

A reaction equation with molecules and salts (possibly also with metals) together is very demanding for the initial lessons. How to proceed and also how to comply with the law of conservation of mass follows in this screencast. Original: "Wolfgang Dukorn" Original: German. All translations in this

The formation of the Alps

The Alps are Central Europe's highest mountains, towering as high as 4800 meters. Today, mainly the harsh weather shapes the Alps. But the forces that formed these mountains came from within the Earth. Author: ZDF/Terra X/Bilderfest/Florian Breier, Christian Stiefenhofer/Michi Kern/Klaus Wache/Tob

08 Salt formation from the elements

Sodium reacts with chlorine to form a white salt, sodium chloride. An ionic bond of cations and anions is formed. It is explained how the PSE helps to determine the charges of the ions and to establish the ratio formula from them. Original: "Wolfgang Dukorn" Original: German. All translations in t

Formation of the Baltic Sea

20,000 years ago, the Baltic Sea region was still covered by a glacier. A change in climate caused the glacial ice to melt. The first form of the Baltic Sea emerged: a freshwater lake. Today, despite its connection to the North Sea, it is considered an inland sea. Author: ZDF/Terra X/Nina Zorn/Anna
