During the lecture Lavelle stated that d-block elements form cations with different oxidation numbers. My question is how do you find the oxidation numbers and what does it mean?

D block elements are transition metals which do not always have the same oxidation number. The oxidation number will usually be specified. Sometimes +2 or +1 will be written, but the oxidation number can also be shown in a compound name, usually in Roman numerals. There are a few exceptions that always have the same oxidation number. For example, zinc will always be +2.
