The smallest particle of a compound that has all the chemical properties of that compound. Molecules are made up of two or more atoms, either of the same element or of two or more different elements. Ionic compounds, such as common salt, are made up not of molecules, but of ions arranged in a crystalline structure. Unlike ions, molecules carry no electrical charge. Molecules differ in size and molecular weight as well as in structure.
Compounds are comprised of species whose electronegativities differ by 3.5 or more. The individual components when dissociated are called ions. Molecules are comprised of species whose electronegativities are within the 3.5 range. They more or less share the electrons between them and contain covalent bonds.

atoms
Does the melting rate depend on the amount of solute added?
Yes, adding a solute to a solvent can affect the melting rate. When a solute is added, it disrupts the crystal lattice structure of the solvent, which can either increase or decrease the melting rate depending on the specific solute-solvent interaction. Generally, adding a solute lowers the melting point of the solvent and can lead to a faster melting rate.
How do scientists know that atoms and molecules combine in well ordered arrays?
Scientists use techniques such as X-ray crystallography to determine the atomic structure of materials. By studying the diffraction pattern of X-rays passing through a crystal, scientists can infer the spatial arrangement of atoms and molecules in the material. This provides evidence that atoms and molecules combine in well-ordered arrays.
