Detailed explanation-1: -Most of the metals are solids under “ordinary” conditions (i.e., 25ºC, 1 atmosphere of pressure, etc.), with the exception of mercury (Hg, element 80), which solidifies at-39ºC, and is a freely-flowing liquid at room temperature.
Detailed explanation-2: -At room temperature most elements are in SOLID phase of matter.
Detailed explanation-3: -Iodine exists as solid at room temperature.
Detailed explanation-4: -Some substances exist as gases at room temperature (oxygen and carbon dioxide), while others, like water and mercury metal, exist as liquids. Most metals exist as solids at room temperature. All substances can exist in any of these three states.
Detailed explanation-5: -Solids: particles vibrating in a fixed regular geometric pattern. (Crystal lattice structure) Most elements exist as solids at STP.
