what is water made of

What do you mean by "made of"? If you are referring to its chemical composition, then it is "made of" one oxygen and two hydrogen atoms, commonly called H2O.

Water is made up of molecules consisting of two hydrogen atoms bonded to one oxygen atom, forming the chemical formula H2O. To understand what water is made of, we need to break down its molecular composition.

Step 1: Identify the elements in water:
Water consists of two types of atoms: hydrogen (H) and oxygen (O).

Step 2: Determine the ratio of atoms:
In the chemical formula H2O, the number "2" indicates that there are two hydrogen atoms bonded to one oxygen atom. This means that for every water molecule, there are two hydrogen atoms and one oxygen atom.

Step 3: Understand the nature of the bond:
The hydrogen and oxygen atoms in water are connected through covalent bonds. A covalent bond is formed when two atoms share their electrons to stabilize their electron configurations.

Step 4: Visualize the water molecule:
The structure of a water molecule can be visualized as an oxygen atom at the center, with two hydrogen atoms bonded to it, forming a bent or V-shape structure. The oxygen atom has a slightly negative charge, while the hydrogen atoms have slightly positive charges, creating a polar molecule.

In summary, water is made up of two hydrogen atoms bonded to one oxygen atom in a covalent bond, forming the molecule H2O.
