Why is the total mass of a helium nucleus not equal to the mass of its individual parts?
(Points : 3)

The "missing" mass is due to inaccurate measurement on a very small scale.

The "missing" mass has been converted to energy.

The "missing" matter has been converted to mass.

The "missing" mass has been converted to matter.

I would guess the first one

This question goes along with what is known as binding energy. Based on this concept, it is noted that the whole is lesser than its individual parts. If you split the compound apart, energy is used. Energy and mass are associated due to Albert Einstein's equation of E = mc^2. Therefore, the answer choice that best fits this would be the second choice.

I chose the first one because I read that the whole was less than its individual parts so in brain that led to the first one. Thank you for clarifying. :)
