there are 7 : H2 N2 O2 F2 Cl2 Br2 & I2
All elements can exist as individual atoms in excited states. However, at standard temperature and pressure, hydrogen, nitrogen, oxygen, fluorine, chlorine, bromine, and iodine exists as diatomic molecules.
A diatomic molecule is a molecule made up of two atoms.
because they are Diatomic molecule. H2, O2 etc.
A chemical family whose members exist as reactive diatomic molecules in the gaseous phase is the halogen family. All halogens are considered as toxic.
4 atoms in total. Oxygen is a diatomic molecule, so there is 2 atoms per molecule.
All elements can exist as individual atoms in excited states. However, at standard temperature and pressure, hydrogen, nitrogen, oxygen, fluorine, chlorine, bromine, and iodine exists as diatomic molecules.
Because N exist as diatomic molecule in nature.It is not a noble gas
There are 2 atoms which make up a single molecule of a halogen. Fluorine, Chlorine, Bromine, Iodine and Astatine all exist as X2 , or diatomic molecules.
Diatomic molecules are formed from two atoms, different or identical.
diatomic moleculeA molecule containing two atoms is a diatomic molecule. These types of molecules can also contain more than two atoms.
There are 2 atoms which make up a single molecule of a halogen. Fluorine, Chlorine, Bromine, Iodine and Astatine all exist as X2 , or diatomic molecules.
diatomic molecule
The Halogens (Fluorine, Chlorine, Bromine, and Iodine) exist as diatomic molecules, as do hydrogen, nitrogen, and oxygen.
Two atoms are contained a single diatomic molecule. Elemental Hydrogen is an example of this where two hydrogen atoms share their only electrons in a single covalent bond.
A diatomic molecule is a molecule made up of two atoms.
You think probable to diatomic molecules as: O2, N2, Cl2, Br2, I2, F2, H2.
The were not invented, they exist. Atoms and molecules were discovered.
