Hydrogen is a highly flammable gas, typically obtained by splitting water (H2O) into hydrogen and oxygen. It's very reactive, and is the key ingredient in all acids. When mixed with air it becomes explosive. It's never found as single molecules, but instead exists as the molecule H2. It's a key constituent of most living things.
