Astudent claims that the more valence electrons an element has, the more reactive it is. which is an accurate counterargument to this student's claim?

The wave shown on the electromagnetic spectrum disturb the medium it passes through a)different frequency. b)the same frequency .

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.
