Why are the elements on the periodic table not arranged by mass?
a. similar elements have such different masses that this would lead to a completely random arrangement of elements.
b. atoms are so small that it would make little sense to talk about their masses.
c. this would not allow all of the elements with similar properties to be lined up with each other.
d. atoms with similar masses are so different from each other that this would lead to a random arrangement of atoms.

One of the hopes for solving the world's energy problem is to make use of the fusion reaction 21h +31h --> 42he + 10n + energy how much energy is released when 1 mol of deuterium is fused with 1 mol of tritium according to the above reaction? the masses of the atoms and the neutrons are as follows: 21h = 2.0140 amu 31h = 3.01605 amu 42he = 4.002603 amu 10n = 1.008665 amu. the speed of light is 2.9979 x 108 m/s.
