The mass number of an atom is the total number of protons and neutrons in a nucleus.

And the atomic number is number of protons found in the nucleus.

There are two types of beta decay-

) decay -a neutron is converted to a proton, and electronis

define mass defect and binding energy how does binding energy per nucleon vary with mass number? what is its Significance

Charvi Nayyar 12th Feb, 2020

Hello aspirant

The rest mass of the stable nucleus of a stable atom is always less than the sum of the masses of constituent nucleons.

The difference is called the mass defect Δm (i.e., Δm.c 2 ) which is utilised in keeping the nucleons bound together. This energy is known

which isotope is used to predict the age of Archaeological findings?

Akram Khan 11th Feb, 2020

Hi,

The C-14 isotope is used to predict the age of archaeological findings. It is an isotope of carbon.

The radioactive disintegration of isotope C-14 occurs through a first order kinetics and half life of this isotope is 5,730 years. As all the organic archaeological findings have carbon in them
