CH-221: Chemistry of elements s and p

Introduction to the chemistry of the s & p elements of the periodic table. ...

Description

This lecture covers the chemistry of oxygen and phosphorus, including their properties, compounds, and industrial applications. It discusses the different allotropes of oxygen, the role of phosphorus in nature, and the preparation of various phosphorus compounds. The presentation also delves into the historical significance of arsenic, antimony, and bismuth, highlighting their properties and uses. Furthermore, it explores the toxicology of arsenic and the discovery of oxygen by Joseph Priestley and Antoine Lavoisier. The lecture concludes with a discussion on the paramagnetic properties of oxygen and the chemistry of the ozone layer.

Allotropes of phosphorus

Elemental phosphorus can exist in several allotropes, the most common of which are white and red solids. Solid violet and black allotropes are also known. Gaseous phosphorus exists as diphosphorus and atomic phosphorus. White phosphorus, yellow phosphorus or simply tetraphosphorus () exists as molecules made up of four atoms in a tetrahedral structure. The tetrahedral arrangement results in ring strain and instability. The molecule is described as consisting of six single P–P bonds. Two crystalline forms are known.

Ozone layer

The ozone layer or ozone shield is a region of Earth's stratosphere that absorbs most of the Sun's ultraviolet radiation. It contains a high concentration of ozone (O3) in relation to other parts of the atmosphere, although still small in relation to other gases in the stratosphere. The ozone layer contains less than 10 parts per million of ozone, while the average ozone concentration in Earth's atmosphere as a whole is about 0.3 parts per million.

Old media

Old media, or legacy media, are the mass media institutions that dominated prior to the Information Age; particularly print media, film studios, music studios, advertising agencies, radio broadcasting, and television. Old media institutions are centralized and communicate with one-way technologies to a generally anonymous mass audience. By definition, it is often dichotomized with New media, more often computer technologies that are interactive and comparatively decentralized; they enable people to telecommunicate with one another, due to their mass use and availability, namely through internet.

Media bias

Media bias is the bias of journalists and news producers within the mass media in the selection of many events and stories that are reported and how they are covered. The term "media bias" implies a pervasive or widespread bias contravening of the standards of journalism, rather than the perspective of an individual journalist or article. The direction and degree of media bias in various countries is widely disputed.

Word

A word is a basic element of language that carries an objective or practical meaning, can be used on its own, and is uninterruptible. Despite the fact that language speakers often have an intuitive grasp of what a word is, there is no consensus among linguists on its definition and numerous attempts to find specific criteria of the concept remain controversial. Different standards have been proposed, depending on the theoretical background and descriptive context; these do not converge on a single definition.
