Alkali metals have 1 valence electron, making them highly reactive. With the exception of hydrogen, they tend to be very soft metals with low melting points. Examples include sodium and potassium.
Alkaline earth metals have 2 valence electrons and also are highly reactive and have high melting points. Examples include calcium and magnesium.
Halogens have 7 valence electrons and therefore are highly reactive. They tend to form compounds in nature. Examples include chlorine and fluorine.
Noble gases have a complete outer shell with 8 valence electrons, making them nonreactive. They are typically colorless, odorless gases. Examples include helium, neon, and argon.
Which group is highly reactive with high melting points?
Alkaline metals
Alkaline earth metals
Halogens
Noble gases
