Which statement about alkali metals are correct?

Alkali metals belong to Group 1 of the periodic table. They are highly reactive and readily lose their outermost electron to form positive ions. Alkali metals have low melting and boiling points. They are soft and can be easily cut with a knife. Alkali metals include elements such as lithium, sodium, and potassium.


Are halogen and alkali metals the same?

No, halogen metals and alkali metals are not the same. They are both groups of elements on the periodic table with distinct chemical properties. Halogen metals are found in Group 17 and are highly reactive nonmetals, while alkali metals are found in Group 1 and are highly reactive metals.
