What is the difference between atoms and molecules?
Atoms are the smallest part of an element that retains the properties of the element.
Molecules are made of two or more atoms bonded together to form one particle with specific characteristics.
All matter is made up of atoms which may combine to form molecules.
Some elements, such as neon, Ne, are made up of single atoms. Other elements, such as oxygen, is made up of molecules. The molecules of oxygen have two atoms of oxygen, O2. The symbol for the oxygen element is O. The symbol or one can say, the formula for the molecules of oxygen is, O2. There is another type of oxygen molecule called ozone, O3. The subscript 3 describes the ozone molecule as having three bonded atoms of oxygen.
These diatomic elements aka diatomic molecules should be memorized. H2, N2, O2, F2, Cl2, Br2, I2,
