Ionic Charges and Element Properties

The video tutorial explains how to determine the charge of ions using the periodic table. It covers the charges of polyatomic and monatomic ions, emphasizing the need to memorize certain charges, especially for transition metals. The tutorial also discusses the predictability of ion charges based on their position in the periodic table, with exceptions for transition metals.

What should you refer to when looking for the charge of a polyatomic ion?

• The electron configuration

• The sheet with common ions

• The atomic mass

• The periodic table

How can you determine the charge of a monatomic ion?

• By its atomic number

• By its electron configuration

• By its column on the periodic table

• By its atomic mass

What charge do elements in the halogen group typically have?

• +1

• -1

• +2

• -2

Which group of elements does not typically form ions?

• Transition metals

• Halogens

• Noble gases

• Alkali metals

What is the typical charge of oxygen in ionic compounds?

• +1

• -2

• +2

• -1

Why is it difficult to predict the charge of transition metals?

• They have a fixed charge

• They do not form ions

• They are non-reactive

• Their charges vary and must be memorized

Which of the following is a common charge for zinc?

• +3

• +1

• -1

What charge does lithium typically have?

• -1

• +2

• +1

• -2

Which element is expected to have a +2 charge?

• Calcium

• Nitrogen

• Fluorine

• Sodium

What is the exception to predicting the charge of a monatomic ion based on its location on the periodic table?

• Alkali metals

• Noble gases

• Transition metals

• Halogens
