Detailed explanation-1: -A water molecule (formally known as dihydrogen monoxide) is composed of two hydrogen atoms and one oxygen atom. But you can’t simply take two hydrogen atoms and stick them onto an oxygen atom. The actual reaction to make water is a bit more complicated: 2H2 + O2 = 2H2O + Energy.

Detailed explanation-2: -A water molecule has three atoms: two hydrogen (H) atoms and one oxygen (O) atom. That’s why water is sometimes referred to as H2O. A single drop of water contains billions of water molecules.

Detailed explanation-3: -A water molecule (H2O) is made up of two hydrogen atoms and one oxygen atom.

Detailed explanation-4: -When atoms of elements collide into each other in space, they can form compounds, such as water. To make water, one atom of hydrogen and one oxygen atom combine to form a hydroxyl ion. The hydroxyl ion can combine with a second hydrogen atom, forming a stable molecule that doesn’t react further.
