When an electron revolves in a stationary orbit then:
(1) It absorbs energy
(2) It emits radiation
(3) Its energy remains constant
(4 )It gains kinetic energy
Ans: Its energy remains constant
energy order of octahedral, tetrahdral, squareplaner.
Polysaccharide or Starch and cellulose They are polymer of monosaccharide. The most significant polysaccharides are starch and cellulose. They have a general formula that is (C
For an electron if the uncertainty in velocity is Δ v , the uncertainty in its position( Δ x ) is given by: (1) hm/ 4 Π Δ b (2) 4 Π / hm Π v
explain zone refining method of purification of silicon
The frequency of radiation emitted when the electron falls from n= 4 to n=1 in a hydrogen atom will be (Given ionization energy of H = 2.18x 10 -18 J atom-1 and h= 6.625x 10-
Merits of atomic fluorescence spectrometry technique: The merit of the AFS methods lies within the greater sensitivity achievable because of low background and interference.
