08 The Noble Gas Configuration

The noble gas configuration is a particularly stable electron configuration. The driving force for many chemical phenomena is this state. It should be remembered again that the nucleus is not altered during chemical reactions. Original: "Wolfgang Dukorn" Original: German. All translations in this

Noble gases and the noble gas configuration

Topics of the video: 0:11 Which gases are noble gases? 0:36 Where can I find noble gases? 1:41 Why are the noble gases called "noble"? 2:27 Atomic construction - according to Bohr's shell model + noble gas configuration and octet rule 3:57 How do other atoms - other elements - achieve the noble gas

08 Electron Config Shorthand

Applying the energy levels all the time takes far too long. Therefore, a simple shorthand notation of the electron configuration was developed. Original: "Wolfgang Dukorn" Original: German. All translations in this video have been done by the alugha AI.

The Octet Rule

The video explains the electron distribution according to Bohr's atomic model of noble gas atoms, the noble gas configuration and the octet rule. Original: "Chemistry and biology - get it!" Original: German. All translations in this video have been done by the alugha AI.

Metal bond

In my video I explain the metal bond. In order to understand them better, I will first go into the noble gas configuration or the noble gas state. Then I explain the actual metal bond using the example of the metal magnesium, what the electron gas is, why the metals conduct electricity and which ele

08 Lewis Formulas Without Practice

How are Lewis formulas (valence formulas) set up? The electron octet (duplet for hydrogen) and the total number of electrons must be observed! Original: "Wolfgang Dukorn" Original: German. All translations in this video have been done by the alugha AI.

08 The ionization energy

In this screencast, I show the relationship between ionization energy and energy levels of the electron shell. 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 The Atomic Shell

In this screnncast, Bohr's atomic model is compared with the energy stage model. Using the aluminum atom as an example, the different energy levels are explained and how they are to be filled with electrons are described. Original: "Wolfgang Dukorn" Original: German. All translations in this video
