Question

Q. With the help of given table 4.1, find out the mass number of oxygen and sulphur atom.
—
Table : Composition of Atoms of the first Eighteen Elements with Electrons Distribution in various shells. ​

Answer 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.
