WebQuestion: 96. Most transition metals share a common oxidation state of +2. Which of the following best explains why? A. Transition metals all have a minimum of two unpaired electrons. B. Transition metals have unstable configurations and are very reactive. C. Transition metals tend to gain electrons when reacting with other elements. WebJul 29, 2024 · Many of the transition metals are among the most abundant elements on Earth. Iron is the fourth most abundant. Titanium comes in 10 th and manganese comes in 13 th. Other transitional metals, like gold and silver, are also abundant, but they don’t rank nearly as high as those previously mentioned. WebCations of the second- and third-row transition metals in lower oxidation states (+2 and +3) are much more easily oxidized than the corresponding ions of the first-row transition metals. For example, the most stable compounds of chromium are those of Cr(III), but the corresponding Mo(III) and W(III) compounds are highly reactive. bosch 100 series dishwasher made
