Question

Two Exceptions to the Pattern on the Periodic Table

A) Noble Gases
B) Transition Metals
C) Alkali Metals
D) Lanthanides and Actinides

Answer 1

The two exceptions to the pattern on the periodic table are transition metals and lanthanides and actinides.

Step-by-step explanation:

The two exceptions to the pattern on the periodic table are transition metals and lanthanides and actinides. Transition metals are located in groups 3 to 12 of the periodic table and include elements like iron, copper, and zinc. They have variable valence electrons and exhibit characteristics of both metals and nonmetals. Lanthanides and actinides are located in the two rows at the bottom of the periodic table and are known as inner transition metals.
