Chemical Bonding Lab

1) The types of elements that make up the compounds are:
•Calcium chloride- Where calcium is a metal,and chloride is nonmetal.

•Potassium iodide- Where potassium is a metal,and iodine is nonmetal.

•Sodium chloride- Where sodium is a metal,and chloride is nonmetal.

•Citric acid- Where carbon,hydrogen,and oxygen are nonmetals.

•Phenyl salicylate- Where carbon,hydrogen,and oxygen are nonmetals.

•Sucrose- Where carbon,hydrogen,and oxygen are nonmetals.

2) In terms of the periodic trends,non metals have high electronegativity levels and ionization energies and metals have low electronegativity levels and ionization energies. Potassium iodide,Calcium chloride,and sodium are similar because they are all conductors,and they did not melt. Phenyl salicylate,sucrose,and citric acid are similar because they are non metals and contain carbon,oxygen,and hydrogen.

3) Calcium chloride,potassium iodide,sodium cholride are ionic. Citric acid, phenyl salicylate,and sucrose are covalent. Covalent bonds is the sharing of electron pairs between atoms. Ionic bonding a complete transfer of valence electrons between atoms.

4) My results showed that covalent compounds have low melting points and are soluble in ethanol, and very weak conductors of electricity. This lab also showed that ionic compounds are soluble in water,have high melting points,and are good conductors of electricity.
