Covalent bond
There is no such thing as CI2 However, Cl2 is elemental chlorine, which is covalently bonded to form diatomic molecules.
occurs in gas molecules; also known as diatomic elements.
The covalent bond in diatomic oxygen is a double bond and is stronger than the single covalent bond in diatomic chlorine.
The diatomic molecule of bromine is formed.
covalent bond
Every halogen can form their molecules by a single covalent bond.
Hydrogen bonding is really not bonding, but only a polar interaction. H2 [diatomic hydrogen] is an elemental bond in which gas atoms can cohabit.
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.
nitrogen can :)
The valence electrons
nitrogen
An ionic bond is formed when a metal and a non-metal react. Electrons are transferred during this process. Magnesium is a metal and Fluorine is not. So, it forms an ionic bond. I don't believe there is such thing as a diatomic bond, only diatomic molecules which are 2 atoms of an element (O2, N2, etc) Metallic bonds are formed between metals. And in covalent compounds the atoms share the valence electrons.
