Any time you see the Atomic Mass of an element in brackets on the periodic chart, that number represents the mass number of the longest-lived or best-known isotope of that element. In other words there is no stable isotope, i.e. all forms of it are radioactive.
What else can I help you with?
Why is the atomic mass of technetium usually in brackets?
The atomic mass of technetium is typically shown in brackets because technetium has no stable isotopes. Instead, it exists only in radioactive isotopes with varying masses, so the bracketed atomic mass represents the weighted average mass of these isotopes.
