3. In aqueous solution the gallium ion is 3+. the bicarbonate (hydrogen carbonate) ion, HCO3-
Na2CO3 is a metal - polyatomic bond (Na)+1 = metal & (CO3)-2 polyatomic
Chemical bond
"The atoms in polyatomic ions such as hydroxide ion, ammonium ion and sulfate ion, are held together by covalent bonds" Link: http://www.cartage.org.lb/en/themes/sciences/chemistry/inorganicchemistry/Informationbonding/CovalentBond/CovalentBond.htm
An ionic bond is formed between two metal ions, one metal ion and a polyatomic ion, or two polyatomic ions, and the electrons are completely shared. An example is MgSO4 (magnesium sulfate). Magnesium is a 2+ metal and sulfate is a 2- polyatomic ion.
Polyatomic means many atoms. Anions and cations may be polyatomic:-Polyatomic anions include sulfate ion, SO4-, and nitrate NO3-Polyatomic cations include ammonium ion, NH4+
It is in a Ionic bond.
Gallium forms compouds where it is ionic, present as Ga3+ and rarely as Ga+ and it also bonds covalently forming for example digallane Ga2H6, gallium trichloride etc.

Potassium bicarbonate has ionic bonds.
Covalent bond exists
Yes, metallic bonds are polyatomic, in the sense that all the atoms in a given piece of metal share a bond, it's not just a bond between adjacent atoms, as in other types of bonding such as ionic or covalent.
Chemical bond
Sodium bicarbonate is a polar molecule. The Sodium (NA+) creates a positive charge and the Bicarbonate (HCO3-) creates a negative charge. The attract each other creating a ionic bond.
