Where, A = mass number and Z = atomic number
In hyphenated form of isotope, the name of chemical element is written before the mass number.
(b)
Interpretation:
The common between Ca-40 and Ca-41 should be identified.
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:
Where, A = mass number and Z = atomic number
In hyphenated form of isotope, the name of chemical element is written before the mass number.
(c)
