Document Summary
In 1925, schrodinger and heisenberg separately worked out a new theory, quantum mechanics, which is now considered to be the basic theory at the atomic level. It is a statistical theory rather than a deterministic one. An important aspect of quantum mechanics is the heisenberg uncertainty principle. It results from the wave-particle duality and the unavoidable interaction between an observed object and the observer. can be no less than: One form of the uncertainty principle states that the position and momentum of an object cannot be measured precisely at the same time. Another form of the uncertainty principle states that the energy can be uncertain by an amount. According to quantum mechanics, the state of an electron in an atom is specified by four quantum numbers: (cid:1866), (cid:1864), (cid:1865), (cid:1865). The energy levels in the hydrogen atom depend on (cid:1866), whereas in other atoms they depend on (cid:1866) and (cid:1864).
