Which properties of chemical elements can be determined theoretically?
Can one infer unknown properties from known ones?
Assuming I can examine anything at room temperature (solubility in water, hardness, specific gravity, electrical resistance, etc.), is it possible to obtain findings that will only be confirmed in practice later?
Yes, it is possible to close to unknown properties by examining known properties of chemical elements. The theory of chemical elements deals with the explanation of the properties of elements and their compounds based on their atomic and molecular structure. Various models and theories are used to explain and predict the properties of elements and their compounds. By examining known properties of elements, it is possible to draw conclusions about unknown properties and then to examine them experimentally later.
Thanks for the information.
Was the superconductance predicted / predicted?
Yes, the superconduct was predicted before their discovery. In 1927, physicist Fritz London formulated the London pairing correlation postulate, after which electrons are joined together in a superconductor to couples, which leads to a special behavior. This prediction was later developed and experimentally confirmed by John Bardeen, Leon Cooper and Robert Schrieffer in their BCS theorem.
