Normally non-metals but there are exceptions
Metals present in the periodic table are conductors.

A group in Periodic Table is the column of element in periodic table
Group 18
Metals are typically shiny, malleable, and good conductors of heat and electricity. They are found on the left side of the periodic table. Non-metals, on the other hand, are usually dull, brittle, and poor conductors. They are located on the right side of the periodic table.
A vertical column in the periodic table is called a group or family. Elements within the same group have similar chemical properties due to the same number of valence electrons. There are 18 groups in the periodic table.
The group on the periodic table with the poorest conductors is Group 18, the noble gases. These elements, including helium, neon, argon, krypton, xenon, and radon, are characterized by their complete valence electron shells, which make them chemically inert and non-metallic. As a result, noble gases do not possess free electrons to facilitate electrical conductivity, making them excellent insulators rather than conductors.
A column is known as a group in periodic table. There are 18 groups in the modern setting of periodic table. Elements in the same group usually share same chemical properties and striking physical characteristic trends.
Lead is in the group 14 of the Periodic Table.
Chlorine is in Group 17 of the Periodic Table.
Astatine is placed in group-17 in the Periodic Table. Its symbol is At.
Most metalloids are semi-conductors.
