The band of stability curves upward at high atomic numbers due to the fact that excess of neutrons are required due to the repulsion between protons.
Atomic number is the number of protons. As the number of protons (atomic number) increase, the electrical repulsion force, due to the same sign of the protons inside the nucleus, becomes more dominant compared to the nuclear force attractions, then the nucleus needs more neutrons to gain stability.The presence of more neutrons decrease the density of protons which decreases the repulsion among them.
Answer:
is there anything that is a hint? like a picture or a story?
Explanation:
Answer:
Potential difference will be 151.9 volt
Explanation:
We have given capacitance of the capacitor 
Voltage V = 49 Volt
Dielectric constant K = 3.1
We have to find the potential difference
We know that when a dielectric medium is introduced then p[otential difference is increases by k times
As the dielectric constant k = 3.1
So potential difference will be = 3.1×49 = 151.9 volt
