In context of the lanthanoids, which of the following statements is not correct?
DoubtBuddy
Single Choice
Total number of inner transition elements in the periodic table is:
A10
B14
C28
Correct Answer
D30
Solution
The inner transition elements are two series of elements known as the lanthanoids (previously called lanthanides) and actinoids(previously called actinides). They are usually shown below all the other elements in the standard view of the periodic table, but they really belong to periods 6 and 7. The lanthanoid series consists of the 14 elements cerium through lutetium (atomic numbers 58–71), which immediately follow Lanthanum. Likewise, the actinoid series consists of the 14 elements thorium through lawrencium (atomic numbers 90–103), which immediately follow Actinium. Option C is correct.
