Which of the following is true ?A. The half -filled and filled elkectronic configuration are less stable than the other congfiguration having the same number of electronB. The symbols s for the orbitals having `l = 0` has iots origim=n from the term spherical symmetricalC. The insreasing order for the value of e//m (charge //mass) for eletron (e ) proton (p) neatron (n) and alpha partickle (u) is `n it alpha it p it e`D. The energy of photon having wavelength `800 nm` is larger than having `400 nm` |
Answer» Correct Answer - C a. The half -filled and fully -filled electronic configuration are stable it is due to the large exxharge energy b . The symbol s stand for shape-a term used in the characterassion of spectral lines , The symbols p,d,and f stand for principle , differeus , and fundamental respectively d. The expression is `E = hc//lambda`Hence energy and wavelength are inversaly reated |
