Why is the ratio of neutrons to protons greater in the heavier elements?
A)The greater the number of protons,the weaker the proton-neutron strong nuclear force.
B)The greater the number of neutrons,the weaker the proton-neutron strong nuclear force.
C)The greater the number of protons,the greater the electrostatic force of repulsion.
D)The greater the number of neutrons,the greater the electrostatic force of repulsion.
E)There is actually a lesser ratio of neutrons to protons in the heavier elements.

Quizplus · Accepted Answer

In heavier elements, the number of protons is higher, which increases the electrostatic force of repulsion between them. To counterbalance this repulsion and stabilize the nucleus, a greater number of neutrons is needed, which do not repel each other or the protons electrostatically. This is why the neutron to proton ratio is greater in heavier elements.
