The modern periodic metal was formed by a scientist named Dmitri Mendeleev. He arranged the elements on the periodic table by increasing atomic weight. The elements found in the same column are in the same group, while the elements found in the same row are in the same period. The elements...
A transition metal is one of a group of 40 metallic chemical elements in the Periodic Table. They are defined by their electronic structures incorporating d-shell electrons and they are known for their ability to exhibit and move between different oxidation states as a result. Transition metals i...

Transition metal, any of various chemical elements that have valence electrons—i.e., electrons that can participate in the formation of chemical bonds—in two shells instead of only one. They occupy the middle portions of the long periods of the periodi
How to Identify Alkali Metals, Alkaline Earth Metals, and Transition Metals using the Periodic Table To determine to which metal group a given element belongs, follow the steps below. Step 1:Check Group 1A in the periodic table. Group 1A is the first (leftmost)...
ByFrameMaker— On Sep 15, 2011 @valleyfiah- Mercury is one of the most unique elements in the periodic table. The metal is only one of two elements that are liquid at standard temperature and pressure (stp). Mercury also has a very short temperature range between the freezing and boiling ...
