Molecules and Compounds. When atoms come together to form ionic or covalent bonds, they form stable associations that change the properties of either atom alone. These new molecules exhibit unique emergent properties. A molecule exists when two or more atoms join together by forming chemical bonds.
Atoms are basic building blocks of any matter.Combination of these atoms are molecules.Atoms are made of particles called protons, electrons & neutrons.Check this video for fun learning of atomic structure.Interesting animation lesson for children on structure of atoms .Nov 19, 2012
Everything is made of atoms. An atom is the smallest particle of an element, like oxygen or hydrogen. Atoms join together to form molecules. A water molecule has three atoms: two hydrogen (H) atoms and one oxygen (O) atom.
