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
An electron has principal quantum number 3. The number of its (i) sub-shells and (ii) orbitals would be respectively: (1) 3 and 5 (2) 3 and 7 (3) 3 and 9
Mining of petroleum and Petroleum refining (1) Mining of petroleum: Petroleum deposits takes place at varying depth at different places ranging from 500 to 15000 feet. This is
What is the de-Broglie wavelength associated with the hydrogen electron in its third orbit: (1) 9.96x 10 -10 cm (2) 9.96x 10 -8 cm (3) 9.96x 1
give an example of a compound whose empirical formula & molecular formula are same.
lithium and beryllium markedly differ from other members of their respective groups
sho me the s p d f orbitals shape
Principal of radiometric titration
The Ca 2+ and Mg 2+ ions in hard water form scum with soap. Therefore they don''t form lather and therefore don''t clean the dirt.
