hydrogen
hydrogen (H), a colourless, odourless, tasteless, flammable gaseous substance that is the simplest member of the family of chemical elements.

What is element C and H?

The carbon-hydrogen bond (C–H bond) is a bond between carbon and hydrogen atoms that can be found in many organic compounds. This bond is a covalent bond meaning that carbon shares its outer valence electrons with up to four hydrogens. This completes both of their outer shells making them stable.

What symbol does H stand for?

Hydrogen
Hydrogen is the chemical element with the symbol H and atomic number 1. Hydrogen is the lightest element in the periodic table.

Why is H an element?

Hydrogen was first recognized as a distinct element by Henry Cavendish in 1766. Composed of a single proton and a single electron, hydrogen is the simplest and most abundant element in the universe. Hydrogen combines with other elements to form numerous compounds.

Who named oxygen?

When Joseph Priestley discovered oxygen in 1774, he answered age-old questions of why and how things burn.

What does H+ mean in science?

hydrogen ion
H+ = Proton When the Hydrogen atom loses an electron all that is left is a proton. It becomes the positively charged hydrogen ion known as H+. This is the form of Hydrogen that produces the ATP enzyme that powers our cells and mitochondria. The H+ hydrogen ion is the basis of the pH scale. H:– = Hydride.

Which gas is highest in universe?

Hydrogen, most abundant in the universe, is the chemical element with atomic number 1, and an atomic mass of 1.00794 amu, the lightest of all known elements. It exists as a diatomic gas (H2). Hydrogen is the most abundant gas in the universe.
