A symbol basically is a representation of some properties. These representations can be present in any form like mark form, sign form, or word form. It indicates, signifies, or is understood as a representing unit that gives an idea about an object and relationship between the entities. Symbols enable people to go beyond what they already know or see by establishing connections between otherwise disparate ideas and experiences. Let us discuss what is symbol in chemistry. Symbols used in chemistry are the acronyms that are utilized in chemistry for representing chemical elements, different functional groups and chemical compounds (organic and inorganic compounds). The use of chemical symbols is in every branch of chemistry.
Define Symbol in Chemistry
Let us discuss the symbol in chemistry, there are so many symbols that are used in chemistry.
1. Chemical Symbols
2. Reaction Symbols
3. Temperature Symbols
4. Precipitation Symbol
5. Gas Symbol
6. Free radical Symbol
7. Cation Symbol
8. Anion Symbol
9. Wavelength Symbol
10. Light Symbol
Let us define symbol in chemistry one by one.
As we have already discussed, what is a chemical symbol? So, we all know that it is a symbol that represents the elements present in the periodic table. Chemical element symbols are usually composed of one or two letters from the Latin alphabet, with the first letter capitalised. Latin symbols are also used, especially in formulas.
This type of symbol represents the nature of the reaction. The nature of the reaction can be a forward reaction, backward reaction, reversible reaction, exothermic reaction, endothermic reaction.
This symbol is represented by the delta. Temperature symbol is used in chemical reactions that undergo dissociation, melting, transition in the state. It is represented as Δ. Other than these symbols for representing units of temperature like Fahrenheit, Celsius, Kelvin can also be represented by using symbols.
This symbol is used to represent the precipitate formed in the reaction. This symbol is represented by the downward arrow (↓).
The gas symbol is used to represent the nature of a reactant or product formed in the reaction. If any of the reacting entities are present in the gaseous phase, it will be represented by using an upward arrow (↑).
Free Radical Symbol
The free radical symbol is used to represent the free radical involved in the reaction. It is represented by a small dot over the chemical symbol. For example, Cl. represents the free radical of chlorine atoms.
The cation symbol can be written using a positive sign over the chemical symbol. It is formed by losing an electron.
The anion symbol can be written using a negative sign over the elemental symbol. It is formed by gaining an electron.
What is a Chemical Symbol?
The system of symboling in earlier times originated from the Latin and Greek vocabulary. For some elements, the symbols are present in the Latin vocabulary as they were known in ancient times. For example, Pb is the symbol for lead (plumbum in Latin), Hg is the symbol for mercury (hydrargyrum in Greek). While for other elements, the name is given in German vocabulary, as they are not known in roman time. For example, W for tungsten (Wolfram in German).
Chemical Symbols Name
Chemical Symbols of various elements are given below:
The above-mentioned symbols represent the chemistry symbols name.
Berzelius Symbols of Elements
Berzelius was a pioneer in the field of chemical nomenclature, introducing the one and two-letter symbols for chemical elements based on their Latin names (some of which he had to devise himself). “The chemical signs ought to be letters, for the greater convenience of printing, and not to disfigure a printed book,” he argued in a seminal article published in the British journal Annals of Philosophy in January 1814. He went on to detail the main principles for creating such symbols, the majority of which are still in use today, more than 200 years later. Berzelius's symbols are the symbols that we use nowadays, with some modifications. These symbols are the only ones that we use today. Below is a table is given that shows the names of elements and symbols. These symbols are reproduced from Berzelius's system of symboling.
