问答题
Describe briefly the contribution to the present theory of atomic structure made by each of the following.
【正确答案】Bohr was first to postulate a theory which include the concept of discrete energy levels in atom.
【答案解析】
【正确答案】de Broglie predicted wave properties for a stream of electrons
【答案解析】
【正确答案】Heisenberg postulated the uncertainty principe, which states that there is an uncertainty of position and/or momentum for small particles such as electrons
【答案解析】
【正确答案】Hund showed that electrons in degenerate orbitals would remain unpaired as much as possible
【答案解析】
【正确答案】Pauli state that no two electrons in a given atom can have the same set of four quantum numbers.
【答案解析】
【正确答案】Schrödinger postulated the wave equation,which describes the properties of electrons in atoms better than the Bohr theory does.
