Chemistry is the scientific study of the properties and behavior of matter. [1] It is a physical science within the natural sciences that studies the chemical elements that make up matter and compounds made of atoms, molecules and ions: their composition, structure, properties, behavior and the changes they undergo during reactions with other substances.
Several non-metallic elements exist only as molecules in the environment either in compounds or as homonuclear molecules, not as free atoms: for example, hydrogen. While some people say a metallic crystal can be considered a single giant molecule held together by metallic bonding , [ 20 ] others point out that metals behave very differently ...
In supramolecular chemistry, chemical species are structures created by forming or breaking bonds between molecules, such as hydrogen bonding, dipole-dipole bonds, etc. [3] These types of bonds can determine the physical property of chemical species in a liquid or solid state.
to our questions in an instant rather than having to puzzle over a problem and work it out for ourselves, which means it’s very tempting to reach for an instant answer without worry-ing about whether it’s right or not. Moreover, it’s often easier to remember a piece of received wisdom – say a memorable
