What are the extended effects of the lanthanoid contraction on the elements succeeding them?

Options

  1. ADecreased reactivity
  2. BIncreased reactivity
  3. CDecreased size and changed properties
  4. DIncreased size and unchanged properties

Correct answer

C. Decreased size and changed properties

Step-by-step solution

The lanthanoid and actinoid contractions, have extended effects on the sizes, and therefore, the properties of the elements succeeding them in their respective periods
