What does group 12 mean in the periodic table?
Group 12, by modern IUPAC numbering, is a group of chemical elements in the periodic table. It includes zinc (Zn), cadmium (Cd) and mercury (Hg). The further inclusion of copernicium (Cn) in group 12 is supported by recent experiments on individual copernicium atoms.

Why is group 12 not a transition metal?
Ans. Transition metals are those metals who have partially filled d-orbital means not fully filled. But In group 12 elements zn,Cd and Hg have fully filled d-orbital. That’s why they are not considered as transition metals.
Why is mercury in group 12 on the periodic table?
The group 12 elements, whose chemistry is dominated by the +2 oxidation state, are almost always found in nature combined with sulfur. Mercury is the only metal that is a liquid at room temperature, and it dissolves many metals to form amalgams. The group 12 halides range from ionic to covalent.

What is the heaviest element in Group 12?
The heaviest known group 12 element, copernicium, was first created on February 9, 1996, at the Gesellschaft für Schwerionenforschung (GSI) in Darmstadt, Germany, by Sigurd Hofmann, Victor Ninov et al. It was then officially named by the International Union of Pure and Applied Chemistry (IUPAC) after Nicolaus Copernicus on February 19, 2010, the 537th anniversary of Copernicus’ birth.
What are the elements in Group 3 through 12 called?
The 38 elements in groups 3 through 12 of the periodic table are called “transition metals”. As with all metals, the transition elements are both ductile and malleable, and conduct electricity and heat.
What is element 12?
Element Atomic Number 12 Facts. The symbol for atomic number 12 is Mg. The name magnesium comes from the Greek region called Magnesia , a source of magnesium-bearing compounds. Magnesium forms a highly reactive positively-charged cation, Mg 2+. The atomic weight of element number 12 is 24.3050.
