Class : Class 8
E(energy)=m(mass)*c(speed of light in vacuum)2.... speed of light in vacuum=3.00 x 108(10x10x10x10x10x10x10x10).... It means that there is much more energy stored inside the nucleus of an atom than in its valence electrons. The energy released from splitting an atom is much higher than that of breaking electron bonds.

Ans 2:

Class : Class 7
E = mc2. An equation derived by the twentieth-century physicist Albert Einstein, in which E represents units of energy, m represents units of mass, and c2 is the speed of light squared, or multiplied by itself.

Ans 3:

Class : Class 7
in simple terms "Energy equals mass times the speed of light squared." On the most basic level, the equation says that energy and mass (matter) are interchangeable; they are different forms of the same thing. Under the right conditions, energy can become mass, and vice versa.
