Atomic Number Examples All elements on the periodic table have an identifying atomic number. Here are a few atomic number examples: Hydrogen - atomic number 1. Carbon- atomic number 6. Oxygen - atomic number 8. Sulfur - atomic number 16. ...
In a thermonuclear bomb, an additional step means that more of the bomb's explosive power becomes available. First, an igniting explosion compresses a sphere of plutonium-239, the material that will then undergo fission. Inside this pit of plutonium-239 is a chamber of hydrogen gas. The ...
2.1Some applications of hydrogen Hydrogen is the lightest and most common element in the cosmos. Its atomic number is 1. In its elemental state, hydrogen is rare. But it is one of the components of water and vital to life. It is primarily used to create water. Hydrogen gas can be used...

A new method based on the intensity ratio of coherent to incoherent scattering of x-rays has been developed for the determination of low atomic number elements. The method has been used to determine hydrogen and carbon in hydrocarbons, particularly petroleum, and in a matrix containing additional ...

Results of ab-initio scalar relativistic density functional calculations of the interaction between a mono-atomic gold wire (suspended between two gold tips) and a hydrogen molecule, at various stages of wire stretching, are presented. The hydrogen molecule does not bind to the wire until the wire...
