What is the binding energy of one mole of 234th90 if the mass defect is 1.908 g/mol?

The binding energy of one mole of thorium atom is

Explanation:

Binding energy is defined as the energy which holds the nucleus together. It is basically the product of mass defect and the square of the speed of light.

This energy is calculated by using Einstein's equation, which is:

Where,

E = Binding energy of the atom

= Mass defect = 1.908 g/mol =     (Conversion factor: 1 kg = 1000 g)

c = speed of light =

Putting values in above equation, we get:

Hence, the binding energy of one mole of thorium atom is

answer:

technetium is the most reactive. this is followed by silver. the least reactive out of these three elements is strontium.
