Question

alkali metals
alkaline earth metals
transition metals
radioactive metals

Answer 1

The elements in the first group of the periodic table are known as alkali metals. This group includes lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr). Alkali metals are characterized by their high reactivity, particularly with water, and they have a single electron in their outermost shell, which they readily lose to form positive ions.
