Q. 2. With the help of Table 4.1, find out the mass number of oxygen and sulphur atoms.
Answers (1)
For Oxygen:
Number of protons = 8
Number of electrons = 8
Mass number = Number of Protons + Number of neutrons
= 8 + 8
= 16
Hence mass number for Oxygen is 16.
For Sulphur:
Number of protons = 16
Number of electrons = 16
Mass number = Number of Protons + Number of neutrons
= 16 + 16
= 32
Hence Mass number for Sulphur is 32.
