What is the valence of chloride

Chemistry - value easily explained

What you need:

  • chemical periodic table

Explanation of terms of value

  • The value of an element in its original meaning indicates the maximum number of monovalent atoms with which an element can bond at the same time.
  • In chemistry, the technical term for the value of an element is also "valence". The term "valence electrons" refers to the electrons that are able to form a chemical bond.
  • Over time, the concept of value in chemistry was expanded. The bond value, also called binding, indicates the number of existing bonds of an atom within a certain molecule.
  • The electrochemical valence, on the other hand, describes the oxidation number of an atom. This value can differ significantly from the coherence.
  • The ionic valency, on the other hand, only reflects the lack or excess of electrons in an atom or a molecule.
  • In the case of organic compounds, the valency indicates the number of specific functional groups.

Determination of valence in chemistry

  • The classical valence can easily be determined for the first main group elements of chemistry with the help of the chemical periodic table. In the case of metals, the valence corresponds to the main group number. In the case of non-metals, the maximum number of bonds can be determined by the difference between the number of main groups and 8.
  • In the case of higher ordinal numbers, the elements of the 5th and 6th main group can form an additional bond under certain conditions, which is why the value can be increased by 1.
  • The cohesion can easily be determined with the help of a structure drawing. Just count the bonds an atom forms. Even with organic compounds, you can easily determine the value you are looking for by counting them.
  • In order to determine the electrochemical valency in chemistry, the formal charges of the individual atoms that are involved in the bonds must be considered. If the formal charges are added up, you can thereby determine the oxidation number.
