Neutrons are found in atoms of all elements except in: (1) Chlorine (2) Oxygen (3) Argon (4)Hydrogen Ans: Hydrogen
The order of filling of electrons in the orbitals of an atom will be : (1) 3d, 4s, 4p, 4d, 5s, (2) 4s, 3d, 4p, 5s, 4d (3) 5s, 4p, 3d, 4d, 5s
Consider the ground state of(Z= 24) . The numbers of electrons with the azimuthal quantum numbers,l=1 and 2 are, respectively: (1) 16 and 4 (2) 12 and 5
In Bohr series of lines of hydrogen spectrum, the third line from the red end corresponds to which one of the following inter-orbit jumps of the electron for Bohr orbits in an atom
Which type of compounds give witting reactions
Discuss "cohesive energy" and "electron affinity". ‘Cohesive energy’: In a chemical bond, it’s the energy required to dissociate a solid into isolated atoms or molecules as ap
How vilsmeier haack reaction occur
Why a covalent bond is directional? Covalent bond is formed as a result of pairing of two electrons in atomic orbitals of two atoms. Bond then must lie along the direction of
