ALKALI METALS. Group one (EXCEPT HYDROGEN) on the Periodic Table are Alkali Metals.
Sodium is an Alkali Metal
Alkaline Earth Metals are similar to Alkali Metals in their high level of reactivity. Alkaline metals are sometimes shiny and have high melting points.
Alkaline Earth Metals are most known for their ability to withstand high heat in fires, such as the “fires” of the earth’s core.
This group is also well-known for its presence in living organisms. Calcium and Magnesium are both essential to human life. Strontium is essential to marine life and while Radium is radioactive, it is also toxic.
Beryllium is an Akaline Earth Metal

All Halogens are categorized as nonmetals. Halogens are highlyreactive, and by themselves they can be harmful or deadly tohumans or organisms. They frequently combine with alkali metals to make salts (NaCl = table salt).
These elements can be in various states of matter. For example, two of the halogens are gases at room temperature, one is a liquid at room temperature, and others can be solids at room temperature.
All Noble Gases are colorless, odorless gases that are nonreactive.
Since Noble Gases don’t react with other elements, they do not form compounds except in very specific lab conditions.
The boiling point and melting point of Noble Gases are very close together, so Noble Gases are only liquids within a 10 degree range. They have a very low melting point and boiling point, so they are almost always in gas form.
Noble Gases have many industrial uses due to their safe nature. Because they don’t react with anything and are very stable, they are very useful. For example, krypton is used in many high powered gas lasers.
Noble Gas discharge tubes.
Transition metals are those in groups 3-12 on the periodic table. These elements are in the D-block of the periodic table.
Transition metals generally have high conductivity and are quite malleable as well. Like other metals on the periodic table, transition metals are shiny and have high melting and boiling points.
The transition metal gold is believed to be one of the first metals discovered. In fact, chemists in the Medieval age tried to turn other metals into gold (also known as alchemy).
