Why are they called Alkali Metals?
The alkali metals are so named because when they react with water they form alkalies. Alkalies are hydroxide compounds of these elements, such as sodium hydroxide and potassium hydroxide.
Why are they called Halogens?
When these elements react with sodium, they produce salts. The word halogen comes from the Greek roots hal- meaning “salt” and -gen meaning “to produce.”
Why are they called Noble Gases?
They are called noble gases because they are so majestic that, in general, they don't react with anything. For this reason they are also known as inert gases.
Why are they called Transition Metals?
Because they have a place between group 2A and 3A in the main group elements. They transition through the periodic table.
