PLEASE HELP !! Which metals have more than one charge?

How is the charge of these metals represented ?

How do you find the correct charge of the mixed charge metal?

How do you write the name and formula for Binary ionic compounds containing metals with more than one charge ?

Will give brainliest it is a lab from k12 here is the linkfor each metal that participated in a chemical change, write the type of metal it is, based on your examination of the periodic table. type your answer here. (score for question 3: of 5 points) were there any metallic compounds that did not react with either the acid or the base? write the type of metal, based on your examination of the periodic table. type your answer here.
