Transition Metals - Inner Transition Metals
Transition metals are in the d-block and have valence electrons in the d-orbital's. They can form multiple oxidation states and form different ions. Iron, Cobalt and Nickel are ferromagnetic. Inner transition metals are in the f-block and have valence electrons in the f-orbital's. They consist of the Lanthanides and the Actinides. The Actinides are radioactive and mostly synthetic.

The properties of transition and inner transition metals. The following episode looks at Naming Ionic Compounds when the metal contains more than one charge. We look at using both the Classical system and Stock system for naming such ionic compounds. The following episode looks at Naming Ionic Compounds when the metal contains more than one charge. We look at using both the Classical system and Stock system for naming such ionic compounds. Boron Family - Carbon Family - Nitrogen Family
The Nitrogen family, the Carbon family and the Boron family are found in the p-block of the Periodic Table. The Nitrogen family is group 13, while the Carbon family is group 14 and the Boron family is group 15. All of the elements in the Nitrogen, Carbon and Boron families have unique characteristics and are of great chemical importance.
The properties of the boron, carbon and nitrogen families.

Oxygen Family
The Oxygen family, sometimes also known as chalcogens, is group 16 on the periodic table and consisted of oxygen, sulfur, selenium, tellurium, polonium and ununhexium. The elements in this group show patterns in its electron configuration, especially in the outermost shells.
The properties of the oxygen family. Halogens
Halogens are nonmetal elements located on the right side of the periodic table in Group 7. Halogens include the elements of florine, chlorine, bromine, iodine and astatine. Halogens have a negative 1 charge and are considered very reactive.
The properties of the halogens.

Noble Gases
The noble gases are located in the last column on the right side of the periodic table and are some of the most stable elements in the periodic table. The noble gases include helium, neon, argon, krypton, xeon and radon.
The properties of the noble, or inert, gases. Noble Gas
