Question

with the help of table 4.1 find out the mass number of oxygen and sulphur atoms​

Answer 1

Answer:

Explanation:

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
