Ionic and Covalent Bonding Tutorials

Master ionic and covalent bonding! Discover how atoms connect and name compounds in this engaging science activity.

Objectives: You will be able to explain how ionic and covalent bonds form. You will be to model bonds between atoms using the Lewis Dot Diagram, and you will be able to name bonded molecules and compounds. PBS LearningMedia Work through the following simulation. Be prepared to answer questions about ions and ionic bonds below. IONIC Bonding Simulation 1. _ charged atoms are attracted to each other. neutrally positively oppositely negatively 2. Metals tend to loose electrons and form _charged ions. neutrally positively oppositely negatively 3. Non-metals tend to gain electrons and form _charged ions. neutrally positively oppositely negatively 4. We use ratios to write ionic compound formulas. Ratios show us: how many of each atom there are. a neutrally charged atom with equal negative and positive charges. the number of positive and negative atoms in the compound. all of the above. Ionic Bonds Ratio Practice Periodic Table with Valence Electron and Oxidation # Using the above Periodic Table - match the chemical symbol to its number of valence electrons. Na 1 ve Al 3 ve Ar 8 ve S 6 ve Use the drop down box to select the correct ionization charge for the listed elements. Based on the oxidation numbers of elements in the above Periodic Table -Calcium (Ca) would form a +2 ion.Lithium (Li) would form a +1 ion.Nitrogen (N) would form a -3 ion.Chlorine (Cl) would form a -1 ion. How to use Ratios to write out formulas for Ionic Compounds.... Complete the blanks in the following table.Subscript can be created by highlighting the number and right clicking. Element 1 + Element 2 Ratio Formula Mg (+2) S (-2) 1 : 1 MgS H (+1) O (-2) 2 :1 H20 Ca (+2) Cl (-1) 1 : 2 CaCl2 H (+1) N (-3) 3 : 1 H3N PBS LearningMedia Covalent Bonding Tutorial Covalent bonds are formed primarily between what type of elements? metals metalloids non-metals solids Covalent bonds form when atoms share, or more accurately, _ electrons to complete their valence electron shell. swap give take fight over Naming the Molecules. Complete the table below using what you learned from the tutorial. (mono = 1) (di = 2) (tri=3) (tetra = 4) (penta = 5) (hexa = 6) Formula Name SO2 sulfur dioxide Cl2O dichlorine monoxide N2O dinitrogen monoxide O2 dioxide Lewis Dot Model for Chlorine Gas Watch and apply what you learn to drawing a Lewis Dot diagram for the molecule below. Use the drawing tools to create a Lewis Dot diagram for H20.How many valence electrons do EACH hydrogen atom have? How many valence electrons does the oxygen atom have?
