Category:Alkaline earth metals

This category concerns the topic: terms for alkaline earth metals, chemical elements in group 2, which all have two valence electrons.

This category contains no dictionary entries, only other categories. The subcategories are of two sorts:

• Subcategories named like "aa:Alkaline earth metals" (with a prefixed language code) are categories of terms in specific languages. You may be interested especially in Category:en:Alkaline earth metals, for English terms.
• Subcategories of this one named without the prefixed language code are further categories just like this one, but devoted to finer topics.

NOTE: This is a set category. It should contain terms for alkaline earth metals, not merely terms related to alkaline earth metals. It may contain more general terms (e.g. types of alkaline earth metals) or more specific terms (e.g. names of specific alkaline earth metals), although there may be related categories specifically for these types of terms.
