Why sulphur shows catenation

Hence sulphur has great tendency for catenation than oxygen. The s orbital in these elements is completely filled and p orbitals are half filled, making their electronic configuration extra stable. There is a considerable increase in covalent radius from N to P. However, from As to Bi only a small increase in covalent radius is observed. This is due to the presence of completely filled d and f or f orbitals in heavier members. The tendency to exhibit —3 oxidation state decreases down the group due to increase in size and metallic group.

In the last member of the group, bismuth hardly forms any compound in —3 oxidation state. Because of the extra stable half filled p orbitals electronic configuration and smaller size, the ionization enthalpy of the group 15 elements is much greater than that of group 14 elements in the corresponding periods.

However, amongst the heavier elements, the different is not that much pronounced. Uses of Neon: i Neon is mainly used in fluorescent lamps of tubes for advertising purposes. These are known as neon signs and can be seen at long distances even when there is a fog.

Connect and share knowledge within a single location that is structured and easy to search. Oxygen is a rather boring element. It has only two allotropes, dioxygen and ozone. Dioxygen has a double bond, and ozone has a delocalised cloud, giving rise to two "1. On the other hand, sulfur has many stable allotropes, and a bunch of unstable ones as well. The variety of allotropes, is mainly due to the ability of sulfur to catenate. But, sulfur does not have a stable diatomic allotrope at room temperature.

So, why do sulfur and oxygen have such opposite properties with respect to their ability to catenate? First, a note: while oxygen has fewer allotropes than sulfur, it sure has more than two! Many of these actually have a corresponding sulfur variant. However, you are right in a sense that sulfur has more tendency to catenate… let's try to see why! Share This Video.

The catenation may be defined as the property of self-linking. This means the number of atoms of its own type with which it can form stable bonds and can exist. So, it can combine with a maximum of two more atoms.

Similarly, sulphur also catenate. Carbon is known to be the element in which the catenation occurs most readily. It forms covalent bonds to form longer chains and structures with other carbon atoms. This is the main reason behind the occurrence of a vast number of organic compounds in nature. Carbon is most well known for its properties of catenation, with organic chemistry essentially being the study of catenated carbon structures and known as catenae.

Tin is similarly not known to but is a topic of research to identify the catenation property in it but it is equivalent to germanium.

Lastly, lead or Pb which is a metal in the group and catenation property is mostly shown by non-metals that is why it does not show any catenation power. Second-period elements such as Lithium, Beryllium, Boron show a diagonal relationship with third-period elements.

The element of the second period shows some properties similar to the diagonally downward element. So, this relationship is called a diagonal relationship. Boron and silicon are diagonally related. Catenation is the ability of an atom to form bonds with other atoms of the same element.
