The Halogen family.
halogens
Halogens
Fluorine is a gaseous element which exists as diatomic molecules and every element is a pure substance.
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.
Up
Many gaseous elements form diatomic molecules: hydrogen, nitrogen, oxygen, fluorine, chlorine, as well as vapors of other elements not gasses under standard conditions like bromine, iodine, etc.
Do you mean burned or boiled? If it's burned, then there was a chemical reaction, and it's a chemical change. If it was just heated until it boiled... well... that's a bit trickier, you see. The issue is that while boiling is usually a physical change and not a chemical change, the normal state of sulfur at room temperature and pressure is in ring molecules, S8 or higher. However, gaseous sulfur is diatomic molecules, S2. This is technically a chemical change since it involves breaking and reforming bonds, even though in both cases it's elemental sulfur.
A chemical family whose members exist as reactive diatomic molecules in the gaseous phase is the halogen family. All halogens are considered as toxic.
The element's symbols are N and O, the gaseous diatomic molecules are represented by N2 and O2 .
Hydrogen is H2, a diatomic gaseous element
Dilithium is the diatomic molecule (Li2) of lithium in gaseous phase.
Dilithium is the diatomic molecule (Li2) of lithium in gaseous phase.
Sodium does not exist as molecules in the room temperature and pressure because it is a metal. Although it forms diatomic 'molecules' in gaseous phase at very high temperatures.
Fluorine is a gaseous element which exists as diatomic molecules and every element is a pure substance.
Gaseous N2 molecules, because it exists in diatomic form at 1 atm of pressure and 25ºC
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.
Yes. The diatomic molecules of the elements include primarily H2, N2 & O2; Examples of molecular compounds include: H2O, C2H5OH, NH3, CO2, DNA and sugar.
fluoride, but there should be a cation to go with it.
Elements normally do not form "molecules" apart from 3 gaseous elements which form diatomic molecules. However, Sulfur exists in molecules comprising 8 atoms, while Phosphorous exists as a 4 atom molecule.
