There are thousands of examples but sodium and bromine are an example. They would form the ionically bonded sodium bromide. In more general terms a metal and a non-metal tend to form ionic bonds.
Ionic bonds occur between metals and non-metals.
Most commonly, one metal atom and one non-metal atom.
between a metal and a nonmetal is ionic. covalent is between two nonmetals.
chemical and ionic molecules bond together to form ionic bonds
I suppose that you think to a bond between a metal ad a nonmetal, forming a ionic molecule
Ionic bonds form when electrons are transferred (gained and lost) between the atoms of a metal and a non-metal. This results in a positive ion and a negative ion.
Metallic and nonmetallic elements.
sodium and bromine
Does two oxygen atoms for an ionic bond
Only two different atoms with opposite electrical charge can form an ionic bond.
Two atoms will form an ionic bond by the complete transfer of the valence electrons if the electronegativity difference between the two atoms is above 1.7
"Adams" do not form any sort of bond except that of friendship.

Magnesium and iodine react to form the ionic compound magnesium iodide - MgI2.
Sodium and bromine
No, the bond would be nonpolar covalent
could be either ionic bonds or covalent bonds depending on the difference in the electronegativities between the two atoms forming bond.
Covalent bond by sharing
If the difference in the electronegativity between the two atoms is above 1.7, then an ionic bond is formed.
Basically Nicotine is bonding of 2 molecules. The bond in between these two molecule is very weak and so it is IONIC.
Opposite charge. Note that charged molecules are usually referred to as polyatomic ions. For example (NH4)2SO4 would be an example of two oppositely charged polyatomic ions.
