alkali metals
There are a total of 18 groups on The Periodic Table of Elements.
The noble gases.
All groups in the periodic table contain chemical elements.
Transition Metals group 3 to group 12 elements
Meatals: 88 Semimeatals: 6 Nonmeatals: 18 Add: Groups 1 and 18 contain 7 elements. Groups 2, 13-16 contain 6 elements. Groups 3-12 contain 4 elements. Some periodic tables do not include all of the elements 113-118 as only a few atoms of each have been observed in the laboratory.

The periodic table of Mendeleev contain now 118 chemical elements arranged in groups and periods.
Groups are vertical and contain chemical elements with similar properties; periods are horizontal.
There are 18 groups on the periodic table. These groups are columns that contain elements with similar properties due to their shared electron configurations. The groups are numbered 1 to 18, with the first two groups referred to as the "s-block" elements and the last six groups classified as the "p-block" elements.
Omitting the f-block elements, there are 18 groups in the periodic table. Groups 1 and 2 contain s-block elements. Groups 3-12 contain d-block elements and groups 13-18 are made out of p-block elements. The only exception is helium is named under group 18, being a noble gas.
There are a total of 18 groups on The Periodic Table of Elements.
Groups in the periodic table are vertical columns that contain elements with similar chemical properties. Elements in the same group have the same number of valence electrons, which determines their reactivity and chemical behavior. There are 18 groups in the periodic table.
