1) atomic no = 17
mass number = 35
no of protons = 17
no of electrons = 17
no of neutrons = 35-17=18
2) atomic no = 35
mass number = 80
no of protons = 35
no of electrons = 35
no of neutrons = 80-35=45
3) atomic no = 8
mass number = 16
no of protons = 8
no of electrons = 8
no of neutrons = 16-8= 8
4) atomic no =15
mass number = 31
no of protons = 15
no of electrons = 15
no of neutrons = 31-15=16
