The elements of Group 2 in the long periodic table are called alkaline earth metals because:
- Their oxides and hydroxides are alkaline (basic) in nature, meaning they can neutralize acids.
- These metals are found in the earth’s crust as compounds, hence the term “earth” metals.
OR
An example of a transitional element is iron (Fe), and an example of a transuranic element is plutonium (Pu).
