Polyatomic ion ammonium is the exception. When some non-metals contain polyatomic ion ammonium and mix with a metal/metalliod and some times even non-metals the reaction is ionic.
covalent bonds
polar covalent - use the electronegativity difference
In covalent bonding, atoms share electrons to achieve a full outer shell. This contrasts with ionic bonding, where electrons are transferred. One phrase specific to covalent bonding is "electron sharing."
Caffeine is a covalent compound. It is composed of carbon, hydrogen, and nitrogen atoms that form covalent bonds by sharing electrons.
Elements , with the exception of the noble gases which are monoatomic, are either covalent (solids eg diamond, liquid, bromine, gases, e.g. oxygen and nitrogen ) or metals and therefore element's contain covalent or metallic bonds.
covalent bonding is used to share electrons
covalent bonds
Covalent bonding is formed generally between nonmetals.
covalent bonding
Covalent bonding involves the sharing of electrons. Ionic bonding involves the transfer of electrons.
Ionic and covalent bonding involve electrons. Ionic bonding involves the loss and gain of electrons, form ions. Covalent bonding involves the sharing of electrons.

it has covalent bonding
No - pure covalent bonding
Covalent bonding
"Pure Covalent" is a synonym for "nonpolar covalent bonding". That means that each atom pulls equally on the electrons and doesn't produce a permanent dipole moment.
