Molecular Structure of Compounds

1) Chloride of Barium (BaCl2): - The molecular structure of BaCl2 consists of one barium ion (Ba^2+) and two chloride ions (Cl^-) bonded together. - The ionic compound BaCl2 forms a crystal lattice structure due to the strong electrostatic forces between the positively charged barium ions and the negatively charged chloride ions.

2) Potassium Oxide (K2O): - The molecular structure of K2O consists of two potassium ions (K^+) and one oxygen ion (O^2-) bonded together. - Similar to BaCl2, K2O forms an ionic compound with a crystal lattice structure due to the strong electrostatic forces between the positively charged potassium ions and the negatively charged oxygen ions.

3) Ammonium Chloride (NH4Cl): - The molecular structure of NH4Cl consists of one ammonium ion (NH4^+) and one chloride ion (Cl^-) bonded together. - Unlike the previous compounds, NH4Cl is a covalent compound, where the nitrogen and hydrogen atoms share electrons to form the ammonium ion, which then bonds with the chloride ion.

4) Ammonia (NH3): - The molecular structure of NH3 consists of one nitrogen atom bonded to three hydrogen atoms. - NH3 is a covalent compound, where the nitrogen and hydrogen atoms share electrons to form the ammonia molecule.

These molecular structures are essential for understanding the chemical properties and behavior of these compounds in various reactions and applications.
