3 Question 3 (1 point) Vanadium can lose 1 to 5 electrons to give possible positive charges +1, +2, +3, +4, or +5. A previous worker in your lab gave you a vial labelled "Vanadium fluoride", but did not include the chemical formula on the label and did not indicate the charge of the vanadium ion. (Always be complete when you label things!!) The label does indicate that the formula mass is 126.94g/mol. What is the charge of the vanadium...
