In the periodic table of the elements, each column is a group. In chemistry, a group (also known as a family) [1] is a column of elements in the periodic table of the chemical elements. There are 18 numbered groups in the periodic table; the 14 f-block columns, between groups 2 and 3, are not numbered.

2 TbF 3 + F 2 → 2 TbF 4. When TbF 4 and caesium fluoride (CsF) is mixed in a stoichiometric ratio in a fluorine gas atmosphere, caesium pentafluoroterbate (CsTbF 5) is obtained. It is an orthorhombic crystal with space group Cmca and a layered structure composed of [TbF 8] 4− and 11-coordinated Cs +. [35]

In the periodic table of the elements, each numbered row is a period. A period on the periodic table is a row of chemical elements. All elements in a row have the same number of electron shells. Each next element in a period has one more proton and is less metallic than its predecessor.
