Group (periodic table)

set of chemical elements with common periodic properties, appearing as column in the periodic table
(Redirected from Periodic table group)

A group is any column on the periodic table. Elements in the same group usually have similar properties, because they have the same number of electrons in the outermost electron shell. There are eight main groups of elements, numbered 1, 2, and 13-18. The other ten groups are transition metals:

Alkali MetalsEdit

See Alkali metal

The most reactive metals consisting of Lithium (Li), Sodium (Na), Potassium (K), Rubidium (Rb), Cesium (Cs), and Francium (Fr)

  • never include hydrogen.

Alkaline Earth MetalsEdit

See Alkaline earth metal. They consist of Beryllium (Be), Magnesium (Mg), Calcium (Ca), Strontium (Sr), Barium (Ba), Radium (Ra)

Transition groupsEdit

See Transition metals. Transition Metals are the most number of elements in the periodic table. They consist of Iron (Fe), Copper (Cu), Zinc (Zn), Chromium (Cr), Cobalt (Co), Nickel (Ni), Manganese (Mn), Mercury (Hg), Scandium (Sc), Titanium (Ti), Vanadium (V), Silver (Ag), Gold (Au), Cadmium (Cd), Tungsten (W), Platinum (Pt), Yttrium (Y), Molybdenum (Mo) and others.

The noble gasesEdit

The noble gases are the 18th group in the periodic table. They consist of Helium (He), Neon (Ne), Argon (Ar), Krypton (Kr), Xenon (Xe), and Radon (Rn). They were previously called Inert gases due to their inert properties.
