Concept Introduction:
The atomic number is equal to the number of protons of an element whereas sum of number of protons and number of neutrons is equal to mass number.
A form of chemical element having same atomic number but differ by mass number is known as isotopes. In nuclide notation of isotope, the mass number of the isotope is present in superscript in front of the symbol of given element and atomic number is present in subscript in front of the symbol of the element.
The expression is given by:
where, A = mass number and Z = atomic number
(c)
Interpretation:
The atomic number, mass number, number of protons and number of neutrons should be calculated for selenium-75.

Explain the basis of approximating the summation to an integral in translational motion.arrow_forwardQuantum mechanics. In translational motion, the summation is replaced by an integral when evaluating the partition function. This is correct becausea) the spacing of the translational energy levels is very small compared to the product kTb) the spacing of the translational energy levels is comparable to the product kTc) the spacing of the translational energy levels is very large compared to the product kTarrow_forward
