Explanation / Answer

Isotopes:

The atoms of an element with different mass number or atomic mass are called isotopes. They have same number of protons and electrons but different number of neutrons.

137 56Ba 81 (56 protons and 81neutrons.

Number of protons = number of electron = 56

atomic mass of 137 = 56 protons + number of neutrons

number of neutrons= 137-56=81 neutrons

Name of Hg2^2+ Dimercury(2+) ion; Mercurous ion; Dimercury(2+); Dimercury(I) cation;

14 7N

Number of protons = number of electron = 7

atomic mass of 14 = 7 protons + number of neutrons

number of neutrons= 14-7=7 neutrons
