diatomic
Diatomic elements are H, F, O, N, Cl, I, Br and probable At.
A molecule made of two identical atoms is called diatomic.Five diatomic elements exist as gases at room temperature (25oC/298K) and atmospheric pressure:Hydrogen, H2Nitrogen, N2Oxygen, O2Fluorine, F2Chlorine, Cl2One diatomic element is a liquid at room temperature and atmospheric pressure:Bromine, Br2One diatomic element is a solid at room temperature and atmospheric pressure:Iodine, I2
No elements can be made from molecules, because molecules are made from elements instead. If the question is really, "What elements normally occur in nature as diatomic molecules?", the answer is hydrogen, nitrogen, oxygen, fluorine, chlorine, bromine, and iodine.
Monatomic compounds are composed of single atoms and there are no chemical bonds between these atoms. Diatomic compounds are composed of molecules containing two atoms. ... The main difference between monatomic and diatomic compounds is the number of atoms present in those compounds.
Sodium is not diatomic. Sodium is a metallic element that typically exists as individual atoms in its elemental form. Diatomic molecules, on the other hand, are molecules made up of two atoms of the same element bonded together. An example of a diatomic molecule is diatomic oxygen (O2).
No, nickel is a metal element and does not naturally exist as a diatomic molecule. Diatomic molecules are made up of two atoms of the same element chemically bonded together, such as in oxygen (O2) or nitrogen (N2).
Diatomic means consisting of two atoms. In chemistry, diatomic molecules are molecules composed of only two atoms of the same or different chemical elements bonded together. Examples include oxygen (O2) and hydrogen (H2).
Gaseous oxygen at normal Earthly conditions is composed of diatomic molecules. At very high temperatures, these can decompose into individual atoms. In other words that means that it is made of molecules.
diatomic molecule
A diatomic molecule is one made up of two atoms of the same element; for example, in O2 or N2. A molecule made of two different elements is called a heteronuclear diatomic molecule, such as CO or HCl.
