I believe it is Metals. If I may be wrong, please improve...
There are 18 main groups in the modern periodic table of elements.
18
Group 18, also called the noble gases, contains the elements that are nonreactive.
In the periodic table, the elements are grouped according to their properties. Elements in a group has an equal number of valence electrons. So the elements in a group have most common chemical properties.
Groups 15, 16 and 17.
There are 18 main groups in the modern periodic table of elements.
The transition metal group contains elements with the most varied properties. This is because transition metals have multiple oxidation states, can form colorful compounds, exhibit catalytic properties, and have high melting points among other characteristics.
18
There is a total of 17 elements in those groups.
groups 11 and 12
This is the group 18 of the periodic table of Mendeleev.
Representative elements, also known as main group elements, include groups 1, 2, and 13-18 on the periodic table. Group 1 contains alkali metals, group 2 contains alkaline earth metals, and groups 13-18 contain p-block elements. These groups are called representative elements because they display a wide range of chemical properties.
Group 18, also called the noble gases, contains the elements that are nonreactive.
In the periodic table, the elements are grouped according to their properties. Elements in a group has an equal number of valence electrons. So the elements in a group have most common chemical properties.
There are three types of elements: metals, metalloids, and nonmetals. Most elements are metals.
Groups 15, 16 and 17.
There are total 18 groups in the periodic table that contains elements having same properties.
