This Wodór icon is made in Material Design style developed by Google. This style is based on extremely simplified shapes, thin two-pixel lines, and is optimized for 24x24 px. Unlike other vector icon packs that have merely hundreds of icons, this icon pack contains 4,300 icons, all in the same style and quality.
The icon is a rounded square, within which is inscribed a letter H about a third as wide as the square. The icon represents atomic hydrogen, the most abundant and basic atomic element in the universe, itself comprised of one proton and one orbital electron.
