MY Essey

Hydrogen is the lightest element and can be used to lift up the balloons. Since Hydrogen gas is very easy to flame up especially when mixed with Oxygen.It can be dangerous to be used. Hydrogen can also be used as fuel. Hydrogen is one of the cleanest fuels because when it gets burned it turns in to simple water.Hydrogen is an essential part of many chemical processes.Words of me only me no one else just me
