Ionic Bonding:

- In K4[Fe(CN)6], the potassium ions (K+) and the cyanide ions (CN-) are involved in ionic bonding.
- Ionic bonding occurs between a metal and a non-metal, where one atom donates electrons to another atom to form a bond.
- In this compound, the potassium ions donate electrons to the cyanide ions, resulting in the formation of ionic bonds between them.
- The potassium ions lose one electron each and become positively charged, while the cyanide ions gain one electron each and become negatively charged.
- The opposite charges of the ions attract each other and hold the compound together.

Covalent Bonding:

- In K4[Fe(CN)6], the iron atom (Fe) and the carbon and nitrogen atoms in the cyanide group (CN) are involved in covalent bonding.
- Covalent bonding occurs between non-metal atoms, where the atoms share electrons to form a bond.
- In this compound, the iron atom forms covalent bonds with the carbon and nitrogen atoms in the cyanide group.
- The carbon and nitrogen atoms share their electrons with the iron atom, resulting in the formation of covalent bonds.
- Covalent bonding allows for the sharing of electrons between atoms, creating a stable structure.

Coordinate Covalent Bonding:

- In K4[Fe(CN)6], the iron atom (Fe) and the cyanide ions (CN-) are involved in coordinate covalent bonding.
- Coordinate covalent bonding occurs when one atom donates a pair of electrons to another atom to form a bond.
- In this compound, the cyanide ions donate a pair of electrons to the iron atom, resulting in the formation of coordinate covalent bonds.
- The cyanide ions act as a Lewis base by donating their electron pair to the iron atom, which acts as a Lewis acid by accepting the electron pair.
- Coordinate covalent bonding allows for the formation of complex compounds with a central metal ion bonded to various ligands.

In summary, K4[Fe(CN)6] exhibits ionic bonding between the potassium ions and the cyanide ions, covalent bonding between the iron atom and the carbon and nitrogen atoms in the cyanide group, and coordinate covalent bonding between the iron atom and the cyanide ions.
