Which of the following nuclei would be the most stable? a. 10 protons, 13 neutrons b. 10 protons, 14 neutrons c. 10 protons, 15 neutrons d. 10 protons, 12 neutrons

Option (D) is the correct answer.

Explanation:

For a nucleus to be stable, there should be balance between the number of protons and number of neutrons.

That is, when there are too many protons or neutrons then it will cause an imbalance which will lead to disruption in binding energy from strong nuclear forces which will make the nucleus unstable.

Hence, closer is the number of neutrons to the number of protons more stable will be the nucleus.

Thus, we can conclude that a nuclei with 10 protons, 12 neutrons would be the most stable.

answer is: nuclear fusion produces elements that are heavier than helium.

nuclei combine to form a heavier nucleus, releasing energy.  

for example, fusion of hydrogen atoms at the sun.  

this fusion nuclear reaction is in the inner core of the sun and hydrogen (atomic number 1) is conveted into helium (atomic number 2).  

the inner core is the central region of the sun and all solar energy is produced in the core by nuclear fusion.
