elements exist as diatomic molecules at room temperature:
H - Hydrogen
N - Nitrogen
O - Oxygen
F - Fluorine
Cl - Chlorine
Br - Bromine
I - Iodine
elements exist as polyatomic molecules at room temperature:
S - Sulfur (8)
Se - Selenium (8)
P - Phosphorus (4)
Bromine (Br2) is a liquid at room temperature.
Under most readily achieved temperature and pressure conditions, bromine gas exists as diatomic molecules. Bromine is always an element.
Nitrogen, N2
A diatomic element exists as a molecule containing two of its atoms, such as chlorine (Cl2) and bromine (Br2). Elements that are not diatomic include monatomic elements (noble gases such as Ar, Ne) and triatomic elements (ozone, O3).
Pure iodine at room temperature is a highly volatile solid.
No. Tungsten is a metal and so exists as individual atoms. There are 7 diatomic elements: Hydrogen, Nitrogen, Oxygen, Fluorine, Chlorine, Bromine, and Iodine. All can be found on the right side of the periodic table, with the exception of hydrogen, which is in the top left corner.
Fluorine is a gaseous element which exists as diatomic molecules and every element is a pure substance.
Nitrogen
No. By definition an element is not a mixture.
Under most readily achieved temperature and pressure conditions, bromine gas exists as diatomic molecules. Bromine is always an element.
No - chlorine exists as Cl2 and is thus diatomic.
No - chlorine exists as Cl2 and is thus diatomic.
Nitrogen, N2
nitrogen
At room temperature N (N2) is a gas. N, by itself, does not exist at room temperature and standard pressure. It exists as the diatomic gas, N2.
Air is a mixture as it contains more than one substance!
