Interpretation:
Elements represented by the following symbols and indicate which of them would have no stable isotopes.
Concept introduction:
The majority of elements can be found in two or more isotopes. Isotopes differ in mass because they have the same amount of protons but differing numbers of neutrons.
Answer to Problem 72A
(b) Thorium has no stable isotopes.
(c) Francium has no stable isotopes.
(f) Californium has no stable isotopes.
Explanation of Solution
We know that all elements with
Reason for incorrect options (a) Pt has stable isotopes.
(e) Xenon will have stable isotopes.
(d) Titanium has stable isotopes.
Since platinum has the atomic number
Xenon is a noble gas and are stable.
Atomic number of titanium is 22, so it has stable istope.
