(a) Interpretation: Among the given atoms, the isobars and isotopes should be identified. Ca-40, Ca-41, K-41, and Ar-41 Concept introduction: An atom which has different atomic number (number of protons) but same mass number is known as isobars. An atom which contain same number of protons (atomic number) but the number of neutrons is different 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: X z A Where, A = mass number and Z = atomic number In hyphenated form of isotope, the name of chemical element is written before the mass number.

Solution Summary: The author explains that the common between Ca-40 and Ca-41 should be identified.
Among the given atoms, the isobars and isotopes should be identified.
Ca-40, Ca-41, K-41, and Ar-41
Concept introduction:
An atom which has different atomic number (number of protons) but same mass number is known as isobars.
An atom which contain same number of protons (atomic number) but the number of neutrons is different 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: XzA
Where, A = mass number and Z = atomic number
In hyphenated form of isotope, the name of chemical element is written before the mass number.

The vitamin niacin (nicotinic acid, C6H5NO2) can be isolated from a variety of naturalsources such as liver, yeast, milk, and whole grain. It also can be synthesized fromcommercially available materials. From a nutritional point of view, which source ofnicotinic acid is best for use in a multivitamin tablet? Why?
