Symbols of Elements - Even before knowing what elements were, man started extracting them from their ores. A few metals like gold, silver, iron, copper, lead, tin and mercury were used even in the 1 s t century A.D. A mention of them is made in the 'Charaka Samhita' - ..

Even before knowing what elements were, man started extracting them from their ores. A few metals like gold, silver, iron, copper, lead, tin and mercury were used even in the 1 s t century A.D. A mention of them is made in the 'Charaka Samhita' - a medical treatise of ancient India. These..

It is a short hand notation of an element. E.g. sodium is denoted as Na..

Symbol - The symbol of an element is a short way of representing an element. Symbols can be formed as follows: 1) By using the first letter of the English name of the element. Hydrogen H Phosphorus P Oxygen O Sulphur S 2) By using the firs..

Symbol: C Atomic number : 6 Atomic mass: 12 (most common isotope) Electronic configuration: 1s 2 ,2s 2 ,2p 2 Position in the periodic table: Period II Group IV Carbon occurs in the free state as well as combined state. The following schematic chart shows the occurrence of carbon in va..

The third row elements are from sodium to argon. The build up of these eight elements proceeds exactly in the same manner as discussed above. Here 3s- and 3p-orbitals are filled in place of 2s- and 2p-orbitals as has been done in case of Li to Ne. For e.g., the electronic conf..

Second Row Elements - In lithium (Z =3), the third electron goes to the next 2s orbital. In Beryllium (Z = 4), the fourth electron fills 2s orbital and in boron (Z = 5), the next electron goes to the next available 2p orbital. In carbon, the sixth electron is also to go into the 2p orbita..
