Answer :
The symbol for the isotope of platinum that contains 116 neutrons is Pt-194.
To identify the isotope of platinum with 116 neutrons, follow these steps:
- Find the atomic number of platinum:
Platinum (Pt) has an atomic number of 78, which means it has 78 protons.
- Calculate the mass number of the isotope: The mass number (A) is the sum of protons and neutrons. For this isotope:
Mass number, A = Number of protons + Number of neutrons
A = 78 + 116 = 194
- Write the isotope symbol:
The symbol for the isotope of platinum with 116 neutrons is: Pt-194
