Given information
Here the number of neutrons present in the fluorine isotope is:
Number of neutrons
We have to determine the isotopic symbol of fluorine.
Step-by-step explanation
Step 1.
In the isotopic symbol of the form (X-A), 'X' represents the chemical element and 'A' indicates the mass number.
Here the atomic number of fluorine is and the number of neutrons is and we have to find out the mass number of fluorine to represent the isotopic symbol.
The sum of atomic number(Z) and neutrons (N) of an atom is called the mass number (A) and it can be shown as:
Hence the mass number of fluorine with neutrons is:
Hence the isotopic symbol of fluorine with neutrons is found to be .
