Diatomic elements are chemical elements whose stable form at STP consists of diatomic molecules, molecules of two covalently bonded atoms of that specific element.
ImprovementMost of all gases, except the nobels, are diatomic elements e.g. H2 O2 F2 Cl2 N2and some others like Br2 and I2 not being gases; all of them have covalent bondings.
To my best knowledge there is only one TRI-atomic element: ozone (O3)
Added:Elements with 4, 6, or 8 atoms also exist:P4 (white tetrahedral phosphor)
C6 (graphite, gray hexagonal grafene, allotropous carbon)
S8 (cyclo-octa-sulfur, with rhombic and monoclinic crystallice forms);
even S12 and S18 have been reported, but sulfur is an amazing exception
A diatomic gas means that, in one molecule of the gas, there are two atoms chemically bonded to each other. An example is oxygen: in one oxygen molecule, there are two oxygen atoms covalently bonded to each other. Other examples include H2, Cl2 and N2.
A diatomic solid is a type of solid that only has two atoms. An example of this type of solid is sodium chloride.
Hydrogen (H2)
Yes, diatomic refers to a molecule comprising of two atoms. Thus nitrogen gas (N2), oxygen gas (O2) and hydrogen gas (H2) are all diatomic. These compounds can also be made up of different elements. Acid-base chemistry aside, hydroflouric acid (HF) and hydrochloride acid (HCl) are also diatomic
Br2 (s) bromine
A monatomic gas has no contribution from vibration to its specific heat. A diatomic gas has both vibration of the two atoms as the stretch and compress the bond between them and can rotate faster or slower. With more ways to store energy than just translational energy, diatomic gases tend to have higher heat capacities.
Chlorine
Nitrogen gas is diatomic.
Oxygen is a diatomic gas.
Yes, nitrogen is diatomic.
The molecule of nitrogen contain two atoms, is diatomic.
A diatomic gas
Nitrogen monoxide is a diatomic gas at standard temperature and pressure.
This gas is nitrogen.
A molecule; for a diatomic gas this would be something like H2 , Cl2 etc. A compound would be CO2 or CH4 for example.
Yes, hydrogen gas exists as a diatomic molecule with the formula H2.
