Hydrogen belongs to no definite group. It forms compounds by either donating an electron like an alkali metal or accepting an electron like a halogen.

Alkali Metals are very reactive and readily form compounds but are not found free in nature. They form salts and alkali (acid-neutralizing) compounds such as baking soda. In pure form, they are very soft metals which catch fire on contact with water.

Alkali Earth Metals are reactive and readily form compounds but are not found free in nature. Their oxides are called alkali earths. In pure form, they are soft and somewhat brittle metals.

An atom has a nucleus, made of protons and neutrons, surrounded by electrons orbiting in cloud-like shells. Smaller shells are surrounded by larger shells.The atomic number is the number of protons in an atom. This determines the chemical properties of the atom.Protons have positive electric charge, neutrons are neutral, and electrons are negative. Normally, an atom has equal numbers of protons and electrons. An ion is a charged atom with more or fewer electrons than protons.The atomic weight of an element is the average number of protons plus neutrons. You can easily estimate the atomic weight: it is usually 2 to 2.5 times the atomic number.An element is a substance made from one or more atoms of the same atomic number. A compound is a substance made from two or more elements chemically bonded.

Halogens are reactive nonmetals and readily form compounds but are not found free in nature. They combine with alkali metals to form salts (halogen means salt-former).
elements.wlonk.com
Noble Gases are inactive, or inert. Each atom has exactly the number of electrons it needs to have a full outer shell, so these atoms almost never bond with other atoms. That is why these are all gases.
elements.wlonk.com
Transition Metals are typical metals: they are strong, shiny, malleable (they can be hammered into shape), flexible (in thin sheets or wires), and they conduct both heat and electricity.
elements.wlonk.com
Poor Metals are usually soft and have low melting temperatures.
elements.wlonk.com
Metalloids are partly like metals and partly like nonmetals. For example, they are semiconductors, which means they conduct electricity in some conditions.B, Si, Ge, As, Sb, and Te are metalloids.
elements.wlonk.com
Nonmetals, in their solid state, are usually brittle (they break rather than bend) and they are insulators of both heat and electricity.
elements.wlonk.com
Actinide Metals are all radioactive heavy metals. They are used mainly for their radioactive properties.
elements.wlonk.com
Rare Earth Metals are all soft metals. They are chemically similar to scandium and yttrium and are difficult to separate from each other.
elements.wlonk.com
Superheavy Elements are all radioactive and short-lived. They are never found in nature and have no uses except atomic research.
