Nuclear Equations in universal context

Prepare yourself for a boring huge chunk of text...

·         Hydrogen is the most common element in the universe, ever. This is due to its very simple structure.

·         Formation of new element takes place in dense gas clouds. (Model)

·         Dense gas clouds are constantly “swirling and moving”.

·         Generally, atoms in the dense clouds may become plasma.

·         Plasma is a mixture of atoms, ions and electrons.

·         Lighter elements form heavier ones in dense gas clouds via fusion.

·         The temperature of gas clouds can vary between 10 and 100 Kelvin. We know this via replicating the reactions that occur in the clouds.

·         Gas clouds do not have a constant density.

·         There’s a gravitational field in the centre of clouds forming great temperature and pressure at the core.

·         Fusion is the joining of 2 nuclei.

·         When fusion occurs, energy is released, provoking more fusion to occur. However this is not classed as a chain reaction.

·         First reactions in gas clouds often include fusion of Hydrogen forming Helium, releasing gamma.

2H1 + 3H1 >> 4He2 + g
·         Fusion can occur between any nuclei.

·         Heavy weight stars have higher temperatures because as they’re heavier, they have a greater gravitational field making them a better element manufacturer.

·         The reason cores are FE is because Iron production doesn’t release any energy as a bi product in order to provoke further fusion to occur.

·         Bigger stars are unstable and may cause SuperNovas.

·         Our sun is a light weighted star.
