How many atoms are in a water molecule?
A molecule is the smallest unit of a substance that has all the properties of that substance. For instance, a water molecule is the smallest unit that is still water. A water molecule can be divided into tiny parts called atoms. This produces two hydrogen atoms and one oxygen atom.

Molecules. Science >> Chemistry for Kids. Any time two atoms join together, they make a molecule. All the stuff around you is made up of molecules. This includes you! You are actually made up of trillions and trillions of different types of molecules. Compounds.

An atom is the smallest unit of an element. All atoms of a single element contain the same number of protons. Atoms cannot be further divided using any chemical method. In contrast, a molecule is the unit of a pure substance. A molecule consists of more than one atom. A given molecule has a constant composition, which means the ratio of different a...
A molecule may consist of two or more atoms of a single element or atoms of different elements. Here are some examples of molecules: 1. H2O (water) 2. N2(nitrogen) 3. O3(ozone) 4. CaO (calcium oxide) 5. CO2(carbon dioxide) 6. C6H12O6(glucose, a type of sugar) 7. NaCl (table salt) 8. Hemoglobin (C738H1166N812O203_S2Fe) 9. Vitamin C or ascorbic acid ...
Molecules are classified according to their composition: 1. Diatomic molecule – A diatomic molecule consists of only two atoms. These may be atoms of a single element (homonuclear) or atoms of different elements (heteronuclear). O2is an example of a homonuclear diatomic molcule. HCl is an example of a heteronuclear diatomic molecule. 2. Polyatomic ...
A compound consists of two or more different elements joined by chemical bonds. water (H2O) and hydrochloric acid (HCl) are compounds. Hydrogen gas (H2) and ozone (O3) are molecules, but not compounds. All compounds are molecules but not all molecules are compounds.
A molecule is electrically neutral. The total number of protons and electrons is the same. An ion contains a different number of protons and electrons. If there are more protons, the ion carries a positive charge. If there are more electrons, the ion carries a negative charge. An ion can start as an atom (O2-) or a molecule (H3O+). You can tell it ...
Examples of substances that are not molecules are atoms and ions: 1. H (hydrogen atom) 2. Ag (silver atom) 3. PO4–(phosphate ion) Additionally, alloys aren’t exactly molecules or compounds, either. This is because an alloy consists of a mixture of metals and nonmetals. The elements may form some chemical bonds, but they don’t associate in a fixed m...

We often think of atoms as tiny spheres, but in fact they are made from smaller particles called protons, neutrons and electrons.
- Atoms. Atoms are the building blocks of all matter. Everything is made of atoms - even yourself. Atoms are the smallest particle of an element A pure substance which is made from only one type of atom.
- Molecules. Molecules are made when two or more atoms chemically bond together. Atoms from different elements can combine. When the atoms are from different elements, the molecule can also be called a compound.
- Drawing atoms and molecules. Atoms can be drawn as circles. But all the atoms of an element need to look exactly the same. When drawing a diagram of molecules made from the atoms of more than one element, different sizes and colours can show the different elements.

Sep 8, 2023 · What’s a Molecule? Imagine the universe is a giant puzzle. The smallest pieces that fit together to make everything are called molecules. They’re like tiny teams of atoms that join forces. Take water, for example. It’s made up of two hydrogen atoms and one oxygen atom who are best buddies.
