Transition Metals! ^-^ http://chemistry.about.com/library/blperiodictable.htm
The periodic table
Newland arranged all the then known elements into seven groups in his 'law of octaves'
yes also known as the families of elements
They are groups
Groups 1-12 on the periodic table are known as the "main group elements" or "representative elements." These groups include elements with varying chemical properties and are found in the s and p blocks of the periodic table. They are important for forming compounds and ions with different valences.
The Periodic Table of Elements
The periodic table
Elements in groups 1 and 2 of the periodic table are known as the alkali metals and alkaline earth metals, respectively. Elements in groups 13-18 are known as the boron group, carbon group, nitrogen group, oxygen group, halogens, and noble gases.
Most elements can have more than one oxidation number, but I think you are looking for the transition elements in groups 3 - 12.
Is the Periodic Table. The columns down are the GROUPS The lines across are the PERIODS.
false The vertical columns are known as groups whereas the horizontal rows are known as periods.
These elements are known as transition metals or d-block elements
Groups. Elements in the same group have similar electronegativity properties.

Elements in groups 1 and 2 are called alkali and alkaline earth metals, respectively. Elements in groups 13 through 18 are known as the boron group, carbon group, nitrogen group, chalcogens, halogens, and noble gases.
