In the sun, two hydrogen atoms fuse into one helium
atom. How does this process produce energy?
Select one:
-A helium atom has slightly less mass than two hydrogen atoms. The mass difference becomes
energy.
-Two hydrogen atoms have two more electrons than a helium atom. These electrons become energy.
-Two hydrogen atoms have one more proton than a helium atom. This proton becomes energy.
-A helium atom has slightly more mass than two hydrogen atoms. This mass difference becomes energy.
