Which group of elements exhibits all three phases of matter at room temperature?

Answer 1

Group 17 (old name: VIIA) contains Bromine and

Group 12 of the transition elements contains Mercury

Both elements are liquids at room temperature, RTP but only Mercury, Hg is a liquid at STP

Answer 2

If you mean collectively...

The halogens do this: at room temperature fluorine and chlorine are gases, bromine is a liquid, and iodine is a solid.

The chalcogens (oxygen family) don't have a liquid, though they have a gas (oxygen) and solids (everything else). The pnictogens (nitrogen family) are the same: nitrogen is a gas, everything else is solid.

The alkali metals just miss it on the other direction: the stable ones are solids, but francium (highly radioactive) would probably be a liquid if it were possible to accumulate enough of it in one piece to tell. However, there's no gaseous alkali metal. If, however, you count hydrogen (not really an alkali metal, though it does, like them, have a single s electron in its outer shell), that removes that difficulty.

Answer 3

Group 17 elements (halogens) such as chlorine, bromine, and iodine exhibit all three phases of matter at room temperature. Chlorine is a gas, bromine is a liquid, and iodine is a solid at room temperature.

Answer 4

halogens

Reason:

Of the halogen family, Group 17 (VIIA), at room temperature F and Cl are gases, Br is a liquid, and I is a solid.

Answer 5

The Halogens, also called group 17 or group 7A.

Answer 6

7th group of Periodic Table the halogensexist in all three states, at room temperature Fluorine and Chlorine are gases Bromine is liquid while Iodine and Astatine are solids.

Answer 7
