Write isotopic symbols in the form X-A (for example, C-13) for each isotope.
(a) the iodine isotope with 74 neutrons
(b) the phosphorus isotope with 16 neutrons
(c) the uranium isotope with 234 neutrons
(d) the argon isotope with 22 neutrons
Here, we have to write isotopic symbols in the form X-A (for example, C-13) for each isotope.
Isotopes are the atoms that have same atomic number, that is number of protons but different number of neutrons. Because of different number of neutrons, atoms may exhibit different physical properties. We represent isotopes as :
Where, ‘A’ represents mass number
‘Z’ represents Atomic number
‘X’ represents the chemical element.
