Hey, we got such a nice lady from homework professor of chemistry. We discuss terminology acids - the names we create formulas and vice versa. The task was around 40 names and formulas, I came across rosin two formulas, which I find strange:
numbers will come good. For me, the formula entered incorrectly, perhaps deliberately. I am of the element can acquire that maximum oxidation number, in which the group in the periodic table is located. Bor is located in the third, and can have a maximum of three. Molybdenum then in the sixth and a maximum of six. In addition, unlike the smallest and largest oxidation number of an element should not be more than eight.
element can acquire that maximum oxidation number, in which the group in the periodic table is located.
This rule applies only to the intransitive elements. For the transition elements it may be completely different, e.g. copper is disposed in the first side of subgroup PSP therefore should vykytovat poue in ox. state I. In fact becomes even more oxidation states.
