Question

Where are the lanthanides and actinides found on the periodic table?

A. Columns 7 and 8
B. Columns 3 - 12, in the center of the table
C. Rows 6 and 7, separated from the rest of the table
D. Columns 1 and 2

Answer 1

C. Rows 6 and 7, separated from the rest of the table

Step-by-step explanation:

The lanthanides and actinides are groups of elements in the periodic table, that are thirty (30) in number. They are separated from the rest of the periodic table, usually appearing as separate rows at the bottom. They are often called the inner transition metals, because they all fill the f-block.

Therefore, the correct option is C

" They are found in Rows 6 and 7, separated from the rest of the table"
