Answer:
the atomic number is 50 and the atomic mass is 118
Explanation:
the atomic number is equal to the protons, in the atomic mass is the number of protons added with the number of neutrons.
The atomic number is 50 and the atomic mass is 118.
The atomic number is equal to the number of protons. So, the atomic number is 50.
The formula for mass number is as follows:-
[tex]Mass\ number=Number \ of protons+number\ of\ neutrons[/tex] ....(1)
Substitute 50 for number of protons and 68 for number of neutrons in the above equation as follows:-
[tex]Mass \ number=50+68\\\\=118[/tex]
So the mass number is equal to 118.
