PHYSICAL PROPERTIES OF THE PERIOD 3 OXIDES These pages explain the relationship between the physical properties of the oxides of Period 3 elements (sodium to chlorine) and their structures. Argon is obviously omitted because it doesn't form an oxide. A quick summary of the trends The oxides The oxides we'll be looking at are: |Na2O |MgO |Al2O3 |SiO2 |P4O10 |SO3 |Cl2O7 | | | | | |P4O6 |SO2 |Cl2O

memorize the different characteristics associated with chemical bonding. If students have difficulties differentiating the characteristics associated with covalent and ionic bonding, they will suffer with future topics and other branches of chemistry. Ionic bonding is a crucial topic to understand within general chemistry reactions. Covalent bonding is a root within Organic and Biochemistry that needs to be understood in order to fully understand the theories and concepts discussed in both forms of
1. What is an ionic bond? Typically an ionic bond occurs between one metal and one non-metal ion. One atom borrows one or more electrons from another atom. An ionic bond is a type of chemical bond that occurs when one atom loses an electron to form a positive ion and the other atom gains an electron to form a negative ion, which then result in attraction. 2. What is a covalent bond? A covalent bond is a bond that occurs when atoms in a molecule share a pair of electrons. For example, “the
lab is to learn to demonstrate a double-replacement reaction of ionic compounds. To accomplish this, two ionic compounds will be mixed together and the product will precipitate out of solution. In this procedure, the product must be precipitated out of the solution and then weighed. For this lab, lead (II) nitrate (Pb(NO3)2) and potassium chromate (K2CrO4) will be reacted together to demonstrate double replacement reaction between 2 ionic compounds. This was shown when chromate replaced the
March 2, 2011 Lab Report Physical Properties of Two Types of Solids SCH3U0 Maggie Liu Abstract The purpose of this lab is to study some of the physical properties of two types of solids – ionic and molecular. The samples used are sodium chloride (ionic) and camphor (molecular). The physical properties studied are odour, hardness, melting point, solubility in water and solubility in 2-propanol. It is observed that some of the physical properties of sodium chloride are no odours, hard, a
What About Chemical Bonds ? Many scientists worked on development of chemical bonds Empodecols,Democritos, Aristo, Dalton and Avogadro …. It was a big issue in ancient times How compounds bonded together ? Their hypothesis help to discover Ionic and covalent bonds The electrons quicken around the core Diffuse object of negatively charged electrons carry the electrical load , Protons and Neutrons lie inside the core Same number of electrons that balances the load but which are positively charged
