Whether you commit to the full weekend or just one day, either way, you do not want to miss out on the epic glory of this stellar line-up. Check out our coverage of Rock the Lake 2016, to see what those of you have tickets are in for.
Part 3. Survey of Period 1: hydrogen H to helium He. Period 1, the shortest period of the periodic table, only consists of two elements, hydrogen and helium. Although the properties of helium match those of the other Noble Gases, hydrogen does not really fit into any group. A brief summary of their properties is given below.
That is to say if a protostar has at least 0.08 times the mass of our sun and has a temperature of at least 107 K, hydrogen fusion can begin in it and it will become a star. Hydrogen fusion is the longest stage in an active stars life and so is considered the main sequence of a star.1]. The other process through which hydrogen can fuse into helium in a star is called the carbon cycle. This process will occur if the star has carbon present with in it and if the stars temperature is 2x107 K or greater. Equations (6)-(11) outline the series of reactions that occur in the carbon cycle.
