The halogens are under group 17 (column 17) on the periodic table. They are in the column right next to the noble gases. They have the highest electronegativity values and typically exist as either anions or diatomic gases. Examples of these elements are fluorine, chlorine, bromine, and iodine.
it dosn't exist in the periodic table of elements
Noble gases: helium, neon, argon, krypton, xenon, radon, ununoctium.
"Gas" is a state of matter, any element has a gas phase if you heat it. However at STP (room temperature) there are 11 gaseous elements in the Periodic Table.====================• hydrogen (H)• nitrogen (N)• oxygen (O)=================== The halides• fluorine (F)• chlorine (Cl)===================The Noble Gasses• helium (He)• neon (Ne)• argon (Ar)• xenon (Xe)• radon (Rn)• krypton (Kr)
A period on the periodic table is a row.This is the horizontal section of the periodic table.
There is no Pg on the periodic table.

A group in Periodic Table is the column of element in periodic table
It is called the Periodic Table of Elements.
No, it is not on the periodic table.
A period on the periodic table is a row.This is the horizontal section of the periodic table.
There are no compounds on the periodic table. The periodic table only lists elements.
Rock is not an element and therefore is not on the periodic table. Only elements are on the periodic table
