The valence electrons
nitrogen can :)
Every halogen can form their molecules by a single covalent bond.
covalent bond
Only halogens and members of the oxygen group can form diatomic molecules joined by a single covalent bond.
Diatomic oxygen is a diatomic molecule joined by a double covalent bond.
yes
He2 does not exist.Cl2 is joined by a single covalent bond and N2 by a triple covalent bond.That means O2 is the molecule joined by double covalent bond
This category includes all of the following, and there may be other: O2, CO, and NO.
All of the elements hydrogen, fluorine, chlorine, bromine, and iodine have this property.
All halogen molecules (F2, Cl2, Br2, I2) are bonded with a single covalent bond, this bond is not ionic but molecular.ionic molecules (do not exist) are joined. this is because when a diatomic molecule it transforms to a ionic molecule when its joined by a single covalent bond.
covalent molecules
O2 is a double covalent bond (O=O) Cl2 is a single covalent bond (Cl-Cl( N2 is a triple covalent bond (N///N) He does NOT form any bonds, but remains MONATOMIC.
