The elements which are new are temporarily named according to their atomic numbers. Example : 'N' represents Nitrogen, 'O' represents oxygen, etc. Example: 'Ca' representing Calcium, 'He' representing Helium, etc. When the symbol representing an element is denoted by one letter only, it is written in uppercase. Rules or Conventions followed to denote the Element using Symbol The first letter of a symbol is capitalized with the second (or third) letters being in lowercase. The symbol 'Fe' is used to denote Iron, as the Latin word for Iron is "Ferrum". Hence gold is denoted by the symbol ‘Au’. Some symbols of a few elements are derived from their Latin or Greek names. One may ask, ‘How is the symbol of an element derived?’ We can see in the table above that most of the symbols are derived from the elements’ names, by taking either the first or first two letters from the English name of the element. Some symbols have three letters, they generally represent synthesized elements newly, with some being temporarily named like that. (Image will be Uploaded Soon) Symbol of an ElementĪ symbol representing a chemical element is a 'sign' or 'notation' that generally consists of one or two letters. Example: Elements in group 1A are soft metals that react violently with water. Elements arranged vertically in columns are called ‘Groups’ and elements arranged horizontally in rows are called ‘Periods’.įurther elements are grouped as per p eriodic trends and properties.
The latest Periodic Table is based on Henry Moseley's modern periodic law (Henry Moseley is an English physicist). As per the periodic law, the properties of Elements are periodic functions of their atomic numbers. The Periodic Table is made up of 118 Elements.
During his time only half of the elements known to us now were known, and not all of the information about elements was fully known or accurate. This periodic table was based on the atomic mass of the elements. Dimitri Mendeleev is referred to as the Father of the periodic table put forth the first form of the Periodic Table. Scientists, Professionals, Teachers, and Students of Chemistry widely use the periodic table of elements to search for chemical elements.
