Introduction About Molecules and Atoms :
Atoms are basic building blocks of any matter.Combination of these atoms aremolecules.Atoms are made of particles called protons, electrons & neutrons.To know more about Molecules and Atoms,watch Molecules and Atoms Video to learn more .
Molecules and Atoms :
Atoms are building blocks. If you want to create a language, you’ll need an alphabet. If you want to build molecules, you will need atoms of different elements. Elements are the alphabet in the language of molecules. Each element is a little bit different from the rest.It is the smallest unit of a substance. The identity of a substance will be destroyed if its atom is further divided. Different substances will have different types of atoms. All atoms are made up of a number of protons, neutrons and electrons. As an example, diagram (left) below shows a schematic representation of the atom for helium.
Molecule is a group of two or more Atoms that stick together. Molecules (MOLL-uh-cyools) are so small that nobody can see them, except with an electron microscope. Pretty much everything on Earth and other planets is made of molecules, and so is some of the dust in space.
This is the smallest unit of a compound. For example, water is dihydrogen oxide. The water molecule consists of two hydrogen atoms and one oxygen atom which bind together by covalent bonds.
atom – the smallest amount of an element
molecule – two or more atoms that are chemically joined together (H2, O2, H2O, etc…)
