What do you mean by allotropy ? Explain various allotropic forms of group 15 and group 16 elements. i really neeed it
Answers
Allotropes are most prevalent in Group 13 to Group 16 of the modern periodic table. Some of the allotropes can even be more chemically stable than the element itself. Phosphorus belongs to the Group 15 of the modern periodic table.
Complete step by step solution:
Allotropes are two or more forms of the same element existing in the same physical state (either solid, liquid, or gas) that differ from each other in their physical, and sometimes also in chemical, properties. Allotropes is derived from the Ancient Greek word ἄλλος (allos), meaning 'other', and τρόπος (tropos), meaning 'manner, form'. This difference in physical properties displayed by allotropes of an element can be attributed to the fact that the atoms are arranged in different ways inside the molecules.
Phosphorus also shows the property of allotropy or allotropism. It exhibits several allotropic forms but the most common allotropes of are:
White Phosphorus
Red Phosphorus
Black Phosphorus

Answer:
Answer:
The term allotrope refers to one or more physical forms of a chemical element that occurs in the same physical state. Allotropes may show differences in chemical and physical properties. Swedish chemist Jons Jakob Berzelius proposed the concept of allotropy in 1841. The word “allotropy” comes from the Greek word allotropia, which means changeableness.
Explanation:
The element is carbon and the two allotropes are diamond and graphite. Diamond has three-dimensional rigid structure and does not have any free electrons. Hence, it is hard and bad conductor of electricity. Graphite forms hexagonal sheet-like structure and one valency (one electron) with carbon is free. Hence, graphite is soft and a good conductor of electricity.Read more on Sarthaks.com - https://www.sarthaks.com/21702/an-element-of-group-14-has-two-common-allotropes-a-and-b-a-is-very-hard-and-is-bad
