Carbon Dioxide

Submitted by tduke6 on Sun, 24/07/2016 - 21:47

Carbon dioxide is all around us: the bubbles in soda, dry ice for refrigeration and the gas in some fire extinguishers.

Carbon dioxide has a chemical formula of CO2, was 'discovered' in the 1750's by a Scottish physician Joseph Black and makes up 0.04% of the Earth's atmosphere.

In this blog post I will discuss carbon dioxide; the composition, structure and characteristics as well as its emissions.

Hydrogen Cyanide (Hydrogen, Carbon, Nitrogen)

Atoms are the building blocks of all matter that we can touch, affect and be affected by. They each contain varying numbers of protons, electrons and neutrons that make up hundreds of thousands of different elements, molecules and compounds used both by nature and humans. These can range from a simple oxygen molecule (O2) to more complicated compounds such as Methamphetamine, C20H15N. One such molecule is HCN; Hydrogen Cyanide.

Silicon

Submitted by ggris2 on Tue, 19/07/2016 - 14:17
This blog focuses on the silicon atom. It details the composition, structure and characteristics, as well as the many ways in which humans use and depend upon this element. Furthermore, this entry will retell a short history of the silicon atom, from its initial creation, to its discovery, until now. Finally, the blog will give an overview of the process involved in the creation and programming of this atom model below, via VRMath2 software.

Introduction 

Nitrogen is an atom which is also the first element in column 15 of the periodic table (Johnson, 2012). It is part of the group of "other" nonmetal elements (Johnson, 2012). Although air is largely associated as "oxygen", the most common element in air is nitrogen (Johnson, 2012). The Earth's atmosphere is 78% nitrogen gas. Despite the fact that there is a lot of nitrogen in the air, there is very little in the Earth's crust (Johnson, 2012). It can also be found in rare minerals such as saltpeter and can be found in all living organisms on Earth such as plants and animals (Johnson, 2012).

Methane
 
Atoms exist all around us, whether it be in living things, or in inanimate objects. They are the basic building blocks of life. However, an atom comprises of a proton, neutron and electron. Protons are positively charged sub-atomic particles, electrons are negatively charged and neutrons have no charge. Atoms can also combine with compatible atoms, to form molecules. Molecules can either just comprise of an element, one type of atom, or a compound, multiple types of atoms. A common molecule found in the air is methane. Methane is an green house gas that is the seventh most prevalent gas in the ozone layer. Methane is used for heat and light, utilising its flammability. Methane comprises of Carbon and Hydrogen. But how do we actually identify methane in the air? Well there are two ways; the composition and structure, and the characteristics.
