an element in the activity series can replace any element

This series is an important tool that helps in predicting many electrochemical reactions. All metals placed above hydrogen will displace hydrogen from acids while those below it do not displace hydrogen from acids. Elements with high electropositive or electronegative powe..

Functional Elements - The elements, which take part in the metabolic activities of plants, whether essential or non-essential are named as functional elements..

Apart from the salts which flow down to the sea waters due to weathering of the rocks, a variety of sources, such as land and sea volcanic activity, seismic activity, deposit large amounts of minerals and metals in the ocean. Some of these dissolve in the water and may res..

'd' block elements are called transition elements. These elements occupy groups 3 to 12 on the periodic table. There are four series of transitional elements, '3d', '4d', '5d' and '6d' depending on the energy levels of 'd' orbitals. They have a gen..

The f - block elements are also called as inner transition elements. As the last electron enters the f-orbital these elements are called as f - block elements. These are divided into two series. They are: Lanthanides and actinides. Lanthanides are t..

It is quite evident that carbon displays a great propensity in forming a large variety of carbon and hydrogen compounds. But carbon can also form bonds with other elements in a hydrocarbon chain, when one or more hydrogen is replaced by an element like oxygen, nitroge..

Occurrence of Elements in Nature - A large number of elements occur inside or around the earth. Less reactive elements, like platinum, gold, nitrogen, oxygen etc., occur in free (native) state. Chemically active elements always occur in the combined..
