All of them. "Representative elements" means "representative of the group". A group which doesn't have any representative elements would be a largely meaningless group.
Group-1, 2,13-18 include representative elements. Group-1 and 2 contain metals. Group 13-17 contain non metals. Group18 comprises of noble gases.
What else can I help you with?
Are 3-12 elements on the periodic table of elements representative elements?
No, 3-12 elements on the periodic table (group 3 to group 12) are transition metals, not representative elements. Representative elements are found in groups 1 and 2, and 13 to 18 on the periodic table.
Why are elements in the tall columns of the periodic table called representative elements?
They follow a pattern for valence electrons.
Is silicon a representative element?
Yes, silicon is considered a representative element as it falls in Group 14 of the periodic table. Representative elements are those found in the s and p blocks of the periodic table.
Why are elements in the tall columns in the periodic table called representative elements?
Conventionally representative elements are called the chemical elements from the groups 1,2, 13-18. These elements haven't generally variable valencies. The transitions metals are not representative elements.
Is sodium a representative element?
Yes, sodium is a representative element because it belongs to Group 1 of the periodic table, which is known as the alkali metals group. Representative elements are those found in the s and p blocks of the periodic table.

They follow a pattern for valence electrons.
Is nitrogen a transition or representative element?
Nitrogen is a representative element. Transitional elements are those found in the d-block of the periodic table, while representative elements are the s and p-block elements. Nitrogen is located in group 15 (formerly known as group V) of the periodic table.
Is carbon a representative element or transition?
Carbon is a representative element. It is located in group 14 of the periodic table, which is a group of representative elements also known as the "carbon group". Transition elements are typically found in the d-block of the periodic table.
Where is the groups located on the periodic table?
Carbon group is 14th group of Periodic Table and among representative elements it is 4 A group.

Are the elements Cu a representative elements?
Yes, copper (Cu) is considered a representative element. Representative elements also called main-group elements, are the elements found in the s and p blocks of the periodic table. Copper is located in Group 11 and period 4 of the periodic table, making it a representative element.
