Using the Lewis structure that obeys the octet rule, what is the formal charge of sulfur in the SO4^(2-) ion? Why is the periodic table arranged the way it is? Why is hydrogen not a noble gas? Why does the s orbital fill before the p orbitals?
That polonium dioxide is amphotetic is not really remarkable because oxides with the other element in the +4 oxidation state run the gamut from acidic (sulfur dioxide) to basic (thorium dioxide) with some oxides like titanium dioxide showing amphoteric character in between. Incidentally, silicon d...
Ionic compounds are some of the highest melting chemical compounds, which is an indication of the strength of the ionic bonds and the arrangement of the ions called the crystal lattice and unit cell (smallest repeating unit of a crystal lattice). Answer and Explanation: Become ...
