Answer 1

Question:

Two element can exist as :

a)isotope

b)isobar

c) both

d) none

Answer:

a) isotope

Explanation:

All elements have isotopes. In 2 additional cases (bismuth and protactinium), mononuclidic elements occur primordially which are not monoisotopic because the naturally occurring nuclide is radioactive, and thus the element has no stable isotopes at all. For an element to be monoisotopic (mono=single) , it must have one stable nuclide.

Hope it helps.
