1. Atomic orbitals are the quantum states of the individual electrons in the electron cloud around a single atom. Specifically, atomic orbitals are the quantum states of the individual electrons in the electron cloud around a single atom.
2. All The Bohr Model has an atom consisting of a small, positively charged nucleus orbited by negatively charged electrons. Here's a closer look at the Bohr Model, which is sometimes called the Rutherford-Bohr Model.
3. According to the de Broglie concept of matter waves, the matter has dual nature. It means when the matter is moving it shows the wave properties (like interference, diffraction etc.) are associated with it and when it is in the state of rest then it shows particle properties. Thus the matter has dual nature.
