Solids are a type of matter that hold their constituent particles tightly packed by using strong intermolecular forces and short internuclear distance. At low temperatures, the solid particles oscillate at their mean pos... More » Science Chemistry Atoms & Molecules

Every living and non-living component that comprises matter consists of molecules, which are formed from the chemical combination of microscopic particles known as atoms. Unlike atoms, molecules are able to transition fr... More »

Leptons and quarks constitute the smallest particles of matter, based on contemporary evidence in the field of particle physics. Traditionally, the atom was considered as the indivisible form of matter. More »

The atomic theory formulated by the British chemist John Dalton proposes that atoms are indivisible particles comprising all matter; atoms of the same element share identical properties, including shape, size and mass; a... More »

Discrete atoms are atoms that form extremely weak intermolecular forces, explains the BBC. Because of this property, molecules formed from discrete atoms have very low boiling and melting points. More »

Intermolecular forces are responsible for the physical properties of a substance, such as its melting or boiling point, viscosity, solubility, surface tension and evaporation. The types of intermolecular forces are ionic... More »

The forces that hold atoms together are the electrical force and the strong force, which is stronger than the electrical force. The electrical force does the majority of the work of holding atoms together, but the strong... More »
