WebDalton’s Atomic Theory 1. The matter is made up of indivisible particles known as atoms. 2. The properties of all the atoms of a given element are the same, including mass. This can also be stated as all the atoms of an element have identical mass and chemical properties; atoms of different elements have different masses and chemical properties. 3. WebIntramolecular forces are the forces that hold atoms together within a molecule. Intermolecular forces are forces that exist between molecules. Types of intramolecular forces of attraction Ionic bond: This bond is formed by the complete transfer of valence electron (s) between atoms.

Atoms and molecules are responsible for forming tiny sand particles, gargantuan black holes and everything in between. The atom is the most fundamental unit of matter, making up everything that we see around us. It is extremely small, measuring in at less than 0.1 to 0.5 nanometers.
