Question
The curve of binding energy per nucleon as a function of atomic mass number has a sharp peak for helium nucleus. This implies that helium nucleus is ______.
Options
radioactive
unstable
easily fissionable
more stable nucleus than its neighbours
Solution
The curve of binding energy per nucleon as a function of atomic mass number has a sharp peak for helium nucleus. This implies that helium nucleus is more stable nucleus than its neighbours.
Explanation:
The elements that are stable are those that are high on the BE vs mass number curve because they are closely bonded. Additionally, the pieces lower on the plot are looserly bonded and unstable. The helium nucleus appeared as a peak on this map, indicating that it is extremely stable.
