Question

How are energy and mass connected during the formation of an atom?

Answer 1

energy is absorbed so, the mass is increased.
energy is released so, the mass is increased

Answer 2

`E=m*c^2`

Step-by-step explanation:

The equation of special relativity.

So you can see that mass and energy are proportional to each other. E - is energy, m - is mass, c - is a speed of light. Using this formula you can even count the conversion of energy to mass and vise versa.
