Answer 2

Inner transition metals are composed of lanthanides and actinides.

To find the answer to this question, we need to understand what inner transition metals are. Inner transition metals are a subset of metals that are located in the periodic table between groups 3 and 4 of the transition metals. They are further divided into two separate series: the lanthanides and actinides.

To determine which options are correct, we can eliminate the options that are not related to inner transition metals.

Metals are a broad category that includes both transition metals and inner transition metals. So, while inner transition metals are metals, the option "metals" is too general and does not specifically refer to inner transition metals.

Halogens and noble gases, on the other hand, are not related to inner transition metals at all. Halogens are a group of nonmetals found in group 17 of the periodic table, while noble gases are another group of nonmetals found in group 18.

So, based on this information, the correct answer is "lanthanides and actinides."
