Hydrogen-1

=Paragraph:=

My element is Hydrogen, which also can be known as H because that it’s element symbol. Hydrogen used to be used for balloons because less dense then air and also less dense than helium which would make the balloon float well. People stop using hydrogen only when they found out it was flammable and could burn easily. Hydrogen can also be used for metal refining. The founder of hydrogen was Henry Cavendish in 1766. Hydrogen is the smallest element in the Periodic Table of Elements and has an atomic mass of 1 and also an atomic number of 1 as well. Because hydrogen has an atomic mass and number of 1, it has 1 proton, 1 electron, and 0 neutrons! Hydrogen is a gas at room temperature and is classified as a non-metal. Elements classified as non-metals cannot conduct heat very well and there are about 14-16 nonmetal elements. The density of hydrogen is very light because it is a gas; the density of hydrogen is 0.089 g/cmз and would sink in water because the density of water is 1 g/cmз.
