Bromine is the only element that matches this description.
When non metals and metals are combined, the result is an ionic compound. Often, an ionic compound salt.
Most of the metals can occur in the native and combined forms.
Mercury forms amalgams with other metals.
Atoms that form negative ions are non-metals. Non-metals that form ions with a charge of 1- are in Group VII, because they must gain one electron in order to achieve a full shell. In Group VII, the physical states of the elements changes from gas to solid down the group at room temperature. Fluorine and chlorine are gases, bromine is a liquid and iodine is a solid. Therefore, bromine is a liquid at room temperature that forms 1- ions when it combines with a metal.
Garnet commonly forms porphyroblasts.

Metals forms several compounds under various conditions. They will form metallic salts. They will also form alloys when combined with other metals.
Group 17 (7A), the halogens.

A precipitate is a solid which 'falls down' from the solution. Thus silver chloride is the precipitate.
3 is the common answer, but in reality there are 5. In order from coldest to hottest it it Bose-Einstein (most uncommonly known) Solid (commonly known) Liquid (commonly known) Gas (commonly known) Plasma (known)
Water Vaper forms when liquid water evaporates.
The name for Mn2O7 is manganese heptoxide. This is more commonly written as manganese(VII) oxide. This is an inorganic compound that forms a volatile liquid.
