Answer :
Answer:
41.7%
Explanation:
The atomic number of Iodine is 53, 53/127 = 41.7
In an iodine-127 nucleus, the percentage of protons is 41.73%.
Calculations of the percentage of protons:
Based on the given information,
- The mass number of iodine-127 is 127.
- The number of neutrons present is 74.
Mass number refers to the sum of the numbers of neutrons and protons present within a nucleus. Thus, the number of protons present in iodine-127 is,
Mass number = Protons + Neutrons
Mass number = Protons + 74
Protons = 127-74
Protons = 53
Now the percentage of protons in iodine-127 is,
[tex]= \frac{53}{127} * 100\\= 41.73 percent[/tex]
Thus, the percentage of protons in the iodine-127 is 41.73%.
