Why is Group 16 called Chalcogens?
-Group-16 elements are also called chalcogens. They are called so because most of the copper ores have copper in the form of oxides and sulphides . They also contain small amounts of selenium and tellurium. ... So, group-16 elements are named chalcogens.

What element is in Group 12 and period 6?
Zinc group element, any of the four chemical elements that constitute Group 12 (IIb) of the periodic table—namely, zinc (Zn), cadmium (Cd), mercury (Hg), and copernicium (Cn).
Is group 7 and 17 the same?
Group 7 (IUPAC group 17) is a vertical column on the right of the periodic table . The elements in group 7 are non-metals called the halogens .
What is Group 0 called?
The elements in group 0 are called the noble gases . They exist as single atoms .
What is Group 8 called?
The group 8 elements are called noble gases . The members of the noble gases include: Helium, Neon, Argon, Xenon, Krypton and Radon. As these elements are non-reactive, they have applications in shielding other elements from reacting with air.
