the only liquid halide is bromine
Bromine Br Atomic number 35. Number of protons-35 Neutrons-45. Electrons-35
Bromine, group 17; Mercury, group 12. Both are liquids at STP
No element in Group II is a liquid at room temperature. The only elements that are liquid at room temperature are bromine, which is in Group VII, and mercury, which is a transition metal and Lord only knows how your book defines those, but it's almost certainly NOT Group II. (It could, conceivably, be Group IIB, though the whole thing of group numbers is one of the stupider concepts in chemistry, especially since there are at least three mutually incompatible ways of defining them.)
Mercury or HG is an element that is liquid at room temperature and is not a diatomic element.
Mercury is the only metal that is liquid at standard conditions for temperature and pressure
Bromine is the only element acts as a liquid in the room temperature. The upper elements in the same group are gases. Iodine is a solid that can undergo sublimation in room temperature.

If you think to halogens (not halides) bromine is a liquid.
No element in Group II is a liquid at room temperature. The only elements that are liquid at room temperature are bromine, which is in Group VII, and mercury, which is a transition metal and Lord only knows how your book defines those, but it's almost certainly NOT Group II.

Bromine is the only element that is liquid and forms diatomic molecules Br2. Mercury is also an element and is liquid but is monoatomic.
Bromine (Br) is a liquid at room temperature and is a non-metal. The only liquid element that is not a metal is Bromine (Br). There is one other element that occurs in liquid form and that is Mercury (Hg).
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 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.
Mercury is the only metal to be liquid at room temperature.
