experiment is to examine the properties of six common chemicals based upon their inherent molecular properties. Though this experiment‚ we can study and compare the bond properties of these chemicals. This experiment is also an introduction comparison of ionic and covalent bonding through real world testing. The properties of each type of bond will be exploited to the fullest during these tests. MATERIALS Materials required complete the lab: * 6 Watch Glasses * 2 g Calcium Chloride per parts

past (Herringway 1). Greek architecture is distinguished by its three famous column designs known as the Doric‚ Ionic and Corinthian‚ which consist of decorated pediments with a focus on symmetry. The most perfect example of a Doric structure would be the Parthenon (Figure 1)‚ which is a temple dedicated to Athena located on the acropolis in Athens made 2400 years ago. The Doric order was the first style used and can be best described as being simple and structured. The columns consist of no base

or any ionic compound conduct electricity and nonelectrolytes do not conduct electricity. An Ionic compound is formed from the electrical attraction between anions and cations‚ typically a metal with a non-metal‚ except hydrogen. When an ionic compound forms‚ the anion transfers an electron to the cation which creates an electrostatic bond and an electrically neutral compound. Also‚ they readily dissolve in aqueous solutions and are good conductors of heat and electricity. Further‚ ionic compounds

Structure and bonding Ionic bonds are chemical bonds formed through an electrostatic attraction between two oppositely charged ions. Ionic bonds are formed between an metal and a non-metal. The metal loses an electron or electrons form its highest energy level becoming a positively charged Ion and the non-metal gains an electron or electrons in its highest energy level‚ becoming a negatively charged Ion. Covalent bonds are strong bonds between two non-metal atoms. A covalent bond forms when two

of different types and strengths of intermolecular bonds to explain the following: There exists four types of intermolecular bonding‚ they include ionic‚ covalent‚ Van der waals and hydrogen bonding. In order to describe the existence of such bonding you must also understand the concepts of polarity‚ polar and non-polar‚ and electronegativity. Ionic bonds are created by the complete transfer of electrons from one atom to another. In this process of electron transfer‚ each atom becomes a ion that

Given a chemical formula‚ identify it as an ionic or molecular type of chemical compound‚ write the IUPAC name (no common names). 2. Given the IUPAC name of an ionic or molecular compound‚ write the chemical formula associated with it. Materials: Student Provides: The exercises
