What is the chemical symbol for phosphorus?
A. Ph
B. P
C. Po
D. Pp
Correct Answer Is Option = P
Notes / Explanation
The chemical symbol for phosphorus is the single letter P, and a knowledge of the symbols of the elements is one of the basic requirements of the study of chemistry. Every element, which is a basic substance that cannot be broken down into simpler substances by ordinary chemical means, is represented by a short symbol of one or two letters, which gives chemists a convenient and universally understood way of referring to the element. In the case of phosphorus, the symbol is simply the single capital letter P, taken from the first letter of its name, following the practice by which some elements are represented by a single letter. Phosphorus is a chemical element that is a non-metal, and it exists in more than one form, differing in their colour and properties, one of which is notable for its tendency to catch fire very easily and to glow, a property connected with the origin of the name of the element, which is related to the idea of giving light. Because of this property, phosphorus in one of its forms is dangerous and must be handled with great care, and it has been used in the making of items that produce fire and light. Phosphorus is a very important element for living things, being one of the elements that are essential for life. It is a key component of the substances that carry the genetic information in living cells and of the substances involved in the storage and use of energy within the body, and it is an important component of the bones and teeth, which contain compounds of phosphorus that give them their hardness and strength. Because it is essential for living things, phosphorus is an important nutrient for plants, and compounds of phosphorus are widely used in fertilisers to help crops grow, since a supply of phosphorus is necessary for healthy plant growth. Phosphorus is also used in a variety of other products and industrial processes. The study of the elements, their symbols, their properties and their importance for life and industry is a central part of chemistry. For PPSC and other competitive examinations, the key points to remember are that the chemical symbol for phosphorus is the single letter P, that phosphorus is a non-metal that exists in more than one form, one of which catches fire easily and glows, that it is essential for living things and is a component of genetic material, energy-carrying substances, and bones and teeth, and that its compounds are widely used in fertilisers.
