The energy of an electron in orbit of hydrogen atom is : (1) 13.6/n 4 x eV (2) 13.6/n 3 xeV (3) 13.6/n 2 xeV (4)13.6/nx eV Ans:
The ratio between kinetic energy and the total energy of the electrons of hydrogen atom according to Bohr's model is: (1) 2 : 1 (2)1 : 1 (3)1 : - 1 (4)
Electron enters the sub-shell for which (n+l) value is minimum. This is enunciated as: (1) Hund's rule (2) Aufbau principle (3) Heisenberg uncertainty principle (4) P
what is metallurgy
can anyone explain the intermediate compound formation theory in detail .?
Delocalisation of electrons in conjugated system is called resonance. For example there is delocalisation of electrons in benzene ,hence we write kekule structure for benzen.
