Answer :
Answer:
Atomic number of this isotope = 77
Explanation:
Given that,
Mass number = 193
No of neutrons = 116
We need to find the atomic no of this isotope.
We know that,
Atomic mass = No of protons + No. of neutrons
Also, atomic no = no of protons
So,
Atomic mass = atomic no + No. of neutrons
⇒ Atomic no = Atomic mass - no of neutrons
Atomic no = 193 - 116
Atomic no = 77
Hence, 77 is the atomic no of the isotope.
Final answer:
The atomic number of an isotope, which corresponds to the number of protons, is determined by subtracting the number of neutrons from the mass number. For an isotope with a mass number of 193 and 116 neutrons, the atomic number is 77.
Explanation:
The atomic number of an isotope is defined as the number of protons in its nucleus. By knowing the atomic number, one can also determine the element it corresponds to. Given an isotope with a mass number of 193 and 116 neutrons, the atomic number can be calculated by subtracting the number of neutrons from the mass number: Atomic number = Mass number - Number of neutrons Atomic number = 193 - 116 = 77. Therefore, the atomic number of this isotope is 77.
