Transition Metals and Ionic Compounds

The video tutorial explains the role of transition metals in ionic formulas, highlighting their ability to form multiple ions with different charges. It discusses the use of Roman numerals in naming these ions and provides examples of ion formation. The tutorial also includes a review of Roman numerals and guidelines for writing formulas with transition metals.

Which part of the periodic table contains the transition metals?

• The bottom row

• The middle section

• The rightmost column

• The leftmost column

Why do transition metals require Roman numerals in their ionic formulas?

• Because they are always negatively charged

• Because they are located in the middle of the periodic table

• Because they can form multiple ions with different charges

• Because they are always positively charged

What charge does a lithium ion typically have?

• 2+

• 1-

• 1+

• 3+

Which of the following ions can iron (Fe) form?

• Fe1+ and Fe2+

• Fe2+ and Fe3+

• Fe1+ and Fe3+

• Fe3+ and Fe4+

Which transition metal can form the most variety of ions?

• Gold

• Iron

• Manganese

• Calcium

What is the Roman numeral notation for an ion with a 3+ charge?

• I

• IV

• III

• II

How is the ion Mn4+ written using Roman numerals?

• Manganese III

• Manganese II

• Manganese IV

• Manganese V

What is the Roman numeral for the number 5?

• VI

• IV

• V

Which of the following is the correct Roman numeral for 9?

• XI

• IX

• VII

• VIII

Why is it incorrect to use Roman numerals for elements like calcium in ionic formulas?

• Because calcium is always negatively charged

• Because calcium is located in the middle of the periodic table

• Because calcium can form multiple ions

• Because calcium is not a transition metal
