The group 2 of the periodic table of Mendeleev contain the following elements: Be, Mg, Ca, Sr, Ba, Ra.
Nitrogen (N2) is the Group 15 element that exists as diatomic molecules at standard temperature and pressure (STP).
The ONLY liquid elements (at STP) areMercury, Hg, in group 12Bromine, Br, in group 17Notations like ia, iia, ib or iib are not commonly in use, maybe in older books or periodic tables.
i dont now
The element phosphorous (P) is located in group 15, period 2.
At standard temperature and pressure (STP), iodine is a solid while hydrogen is a gas.

Bromine, group 17; Mercury, group 12. Both are liquids at STP
Group 12 of the periodic table contain mercury (Hg).
part of the oxygen group....gas, nonmetal...
Group 17 (old name: VIIA) contains Bromine andGroup 12 of the transition elements contains MercuryBoth elements are liquids at room temperature, RTP but only Mercury, Hg is a liquid at STP

The element phosphorous (P) is located in group 15, period 2.
At standard temperature and pressure (STP), iodine is a solid while hydrogen is a gas.
Argon is a gas at STP.
