During the refinement, difference Fourier synthesis indicated a maximum peak at the 1b (0 0 ) position, which was attributed to the excess of titanium (Ti2) with a refined site occupancy about 0.017(2) leading to a decrease in the residual electronic density. [9][10] Before Winkler published his results on the new element, he decided that he would name his element neptunium, since the recent discovery of planet Neptune in 1846 had similarly been preceded by mathematical predictions of its existence. In mid-1885, at a mine near Freiberg, Saxony, a new mineral was discovered and named argyrodite because of its high silver content. Step 1: Count the total number of valence electrons in SiO2.
