21 In atoms, electrons fill up the sub-shells in order of increasing energy.(a)Fill in the last two boxes in the table below to show the order in which the next two sub-shells are filled.1s 2s2p 3s3p4s energy increases→(2)(b)Electrons in atoms occupy orbitals.(i) Explain the ter...
In the ground state of an atom, an electron enters the orbital with lowest energy first and subsequent electrons are fed in the order of increasing energies. This is called Aufbau principle. The word 'Aufbau' in German means 'building up'. Here, it re...
Draw the diagram showing the elliptical orbits proposed by Sommerfeld for N- shell (n = 4). View Solution Draw Moeller’s chart showing the increasing order of energy levels of various orbitals. View Solution Find the value ofn+lof the orbital 2S. ...
Arrange the following orbitals of H-atom in the increasing order of their energy. 3px,2s,4dxy,3s,4pz,3py,4s View Solution Among the ionsClɵ,S2−andNa⊕, the largest ion is___. View Solution K+,CI−,Ca2+,S2−ions are isoelectronic. The decreasing order of other size is: V...
In order to study the topological features and the microscopic origin of the transition, we have constructed a tight-binding (TB) Hamiltonian as a function of uniaxial pressure. It comprises the s and p orbitals of the two Sn atoms in the unit cell and the d orbitals of the Ba atom (th...
Rank the following elements in order of increasing ionization energy: Ge, Rb, S, Ne A. Ge < Rb < Ne < S B. Rb <S < Ne < Ge C. S < Ne < Ge < Rb D. Rb < Ge < S < Ne E. Rb < Ge < Ne < S Arrange the following elements in order of increasing atomic size...
Electron affinity is the amount of energy required to add an electron to the outermost shell of an isolated gaseous atom. Its units are kJ/mol. Answer and Explanation: (a) order of increasing electron affinity of Ge and Br is: Br > Ge because both Ge and B...
Crystal field splitting:The energy gap between the splitting of d-orbitals of the metal ion in presence of ligands is known as the crystal field splitting(Δ). The magnitude of(Δ)is depends on the nature of metal ions and the ligands. ...
