the elements which are very hot and freeze when very cold ,they are the elements which are gases at room temp.
Because pathogenic bacteria love to grow at room temperature.
There was no such thing. Some "Hollywood Historian" came up with the idea and unfortunately it stuck. The word you're thinking of is vomitorium, but it meant the exits from the Colosseum. When the entertainment was over, the exits would 'spew' out the people and so got the name. It had absolutely nothing to do with a Roman home.
Yes Mercury is a metal and it is a liquid at room temperature.
The exact temperature is not known, but it was taken place between May and September in a cramped room with closed windows, meaning it was very hot.
A room where things like temperature, humidity, air pressure, or even microbial or contaminent content are controlled to meet a specific purpose.
The noble gases
All of the noble gases (group 18) are gases at room temperature. In addition, fluorine, chlorine, oxygen, nitrogen, and hydrogen are gases at room temperature.
Elements in group 18 are gases at room temperature.
All the members of the noble gases family (group 18 of the periodic table) are gases at room temperature.
Carbon dioxide
It is alkali metals
All group 18 elements (the noble gases) exist as monatormic gases at room temperature and standard pressure. All other elements form diatomic gases, if they exist as gas under the specified conditions. Among the listed elements there is only one noble gas: Argon
There is no method to designate such properties. Only symbols with atomic number are mentioned.
There are two that are gases, fluorine and chlorine.
Gases at room temperature
When two or more elements are combined to make a compound, water, the new compound can have completely new properties(water is a liquid at room temperature ,while hydrogen and oxygen (elements in the water) are both gases at room temperature),or they can have similar properties to their elements
elements can combine to form new substances with different properties.
