I have been studying the element Hydrogen. Hydrogen is the most common Element in the universe. It powers stars, and is very flammable. Hydrogen is the lightest Element, and is the only Element that has its own group (meaning Hydrogen does not have another Element that shares many similarities). Hydrogen has the atomic weight of 1.0079,and the atomic number of 1. Hydrogen is colorless, a gas, and is nonmetallic, and was discovered is 1766. I will explain more about atoms and groups in another blog post. Have you ever seen this combination of letters and numbers: H2O? Well H is the abbreviation for Hydrogen, the 2 means that there are 2 hydrogen atoms, and the O stands for Oxogen. With all those combined it becomes water. Here is a picture of the periodic table of Elements. Remember, Hydrogen has the abbreviation of H, see if you can find Hydrogen.
