In order for the product to be a square, another element of the sequence must also be divisible by the same prime; but this implies (iii). From (1) we see that the number of for which (i) occurs is at most . From the union bound we see that the number of for which (ii) ...
Pick an element of each , then we have whenever . In particular, one can find a set in the ultrafilter such that whenever and , and by taking suitable intersections that these sets are nested: . If we now define to equal for (and leave undefined outside of ), one can check that ...
Silicon has total 14 electrons in its isolated atom. The first orbit consists of 2 electrons. The second orbit consists of 8 electrons and the third orbit consists of 4 electrons. As there are four electrons in the outer most orbit of a silicon atom, the silicon is a tetravalent element....
