An example of a phosphorus atom

Introduction:

The following post will be about the element phosphorus and its various properties and uses. It is a very complex atom, with a large number of electrons, protons, and neutrons making it up. Its symbol on the periodic table is P and has an atomic mass of 15. It is found in two main forms: White phosphorus and red phosphorus. It is not found free in nature because it is a highly reactive element.

Sulphuric Acid

Sulphuric acid is a pungent-ethereal, colourless to slightly yellow viscous liquid that is soluble in water at all concentrations. It is highly corrosive, dense and oily and one of the most important of all chemical, prepared industrially by the reaction of water (H2O) with sulphur trioxide (SO3). In different concentrations, the acid is used to manufacture fertilisers, pigments, dyes and detergents as well as in petroleum refining and metallurgical processes. Its most common use is in lead-acid storage batteries. In this blog, there will be a detailed analysis of the use of sulphuric acid, its bonds and characteristics.

Everything contains atoms. Atoms are the basic units of matter and the defining structure of elements. Atoms are made up of three differently charged particles: positively charged protons, neutral neutrons and negatively charged electrons. Protons and neutrons are heavier than electrons and reside in the centre of the atom, called the nucleus.

At the VRMath-2 3D Modelling Workshop at QUT, I created an ammonia molecule. The following blog will explain what ammonia is used for, as well as explaining the structure and uses of the individual atoms that make up the molecule.

Ethane

Ethane, otherwise known as C2H6, is an organic compound which is a colourless, liquefied gas. It provides many uses including those from the industrial and a consumer point of view. Ethane is used in fuel, fuel additives, ion exchange systems, paint additives, pigments, plasticizers, building/construction materials, fabric products, textile products, leather products, food packaging and much more.

Water molecule

Imagine you are sitting with your feet in a pool (filled with liquid water), watching the steam (gaseous water) rise from the spa nearby as you sip a drink from your glass filled with ice cubes (solidified water). Not many other chemical substances can exist in all three states of matter within the same temperature range. In fact, water it is the only substance which naturally occurs in all types. This is why H2O (commonly called water) is one of the most interesting chemical compounds in the universe, as well as being essential for life! (We have never found any organism that doesn't contain H2O)  Apart from being the most abundant compound on the Earth's surface, it has many other unique properties such as it's polar covalent bonds.

Ammonia (NH3) is a molecule which consists of three hydrogen atoms and a nitrogen atom bonded together. It is a colourless, odorous, alkaline gas which is produced when organic materials decompose. This molecule is essential to many plants and animals, as a source of nitrogen. Additionally, bacteria within the intestines can produce the substance. Ammonia has many uses, though it is mostly used in fertilisers and cleaning products.
