Question

26) The Pauli exclusion principle requires that a) both the position and momentum of an electron cannot be known simultaneously very accurately b) the wavelength and mass of a subatomic particle are related by = h/mv c) the wavelength of a photon of light times its frequency is equal to the speed of light d) no two electrons in the same atom can have the same set of four quantum numbers e) an electron can have either particle character or wave character 27) The sum of the oxidation numbers of all the atoms in the dichromate ion, Cr:O,, is: a)-2 b) 0 c)+2 d) +4 e)+6

Explanation / Answer

26)
pauli exclusive principal states that for an electron both momentum and position can not be determine accurately at the same time
so,
option A is correct
27)
sum of oxidation state of all the atom in any compound is equal to the charge on the compound
so,
here, -2 is charge on the compound
Answer : option a
