hydrogen, nitrogen, fluorine
Bromine, Br2, and mercury, Hg, are the only elements that are liquids at room temperature.
No, gases are not the only elements. Elements can exist in different states of matter, including solid, liquid, and gas. There are 118 known elements on the periodic table, each with its own unique properties.
Yes - in fact, most of the elements ONLY exist because they were formed in stars.
There are only two elements. They are hydrogen and nitrogen.
All the elements after uranium exist but excepting neptunium and plutonium (present in the earth crust only in ultratrace concentrations) they are man made.
There are actually only two elements liquid at room temperature: mercury and bromine.
The noble gases, gold and platinum.
Considering also very heavy artificial elements this group doesn't exist.
There are only two elements in ammonia: nitrogen and hydrogen.

Liquids xD
There are 92 elements that exist in nature*. Every heavier element has decayed before our time. Of course, there are more elements in the periodic table, but they are all synthetic elements-they were made in a laboratory. Theoretically, there is no limit on how heavy an element could become-you can always add a proton to the nucleus. However these synthetic elements exist only for a fraction of a second and only in particle accelerators. There are currently 115 known elements.
