covalent Molecular simple covalent Graphite Diamond Diagram of structure Describe how the bonds are formed Melting point amp why Electrical conductivity amp why Solubility amp why. The ions are arranged in a lattice. There is attractive electrostatic forces between the ions which are very strong e.g. sodium chloride ionic lattices. . Give two properties of giant ionic structures. . . Ionic (Atomic) Radii & Coordination Number (CN). Ionic radius: . Hypothetical radius (size) of an ion (. cation. or anion). Calculated values from the bonding distances. CN. Number of one kind of the bond forming ions (atoms) surrounding the other, which are forming the first direct bonding. Sugar (Sucrose) Crystals. Table Salt (. NaCl. ) Crystals. Why Draw in Science?. Because you are told to.. Because while you cannot remember the phone number of your family doctor, you can remember how to get to there and which side of the door the door handle is on.. Co = Together. The Octet Rule. The octet rule says that all atoms want to have eight valence electrons, like the noble gases.. One way that atoms can follow the octet rule is by giving and taking electrons… ionic bonding. Including Naming. Note: We likely won’t make it to covalent nomenclature, this is the one students find FAR easier than ionic. Please refer to the videos and naming hand out for help with this, and as always office hours, discussions, and . COVALENT BOND. bond. formed by the . sharing . of . electrons . Covalent . Bonds. Between nonmetallic elements of similar electronegativity. .. Electronegativity = how badly an atom wants to add an electron (non metals have higher electronegativity). Covalent bonding. Ionic bonding. Ionic Bonding. Bonding as you’ve never imagined it. http://www.youtube.com/watch?v=BCYrNU-7SfA. Objectives. To consider the features of ionic and covalent bonds, and the compounds they make. Bonding Discussion. Bonding. . Ionic. . Covalent. . Metallic. Determined by difference in Electronegativity between atoms.. Ionic . Compounds. Crystalline . solids (made of ions) . High melting and boiling points . SCH4U1. Mr. . Dvorsky. Ionic Solids. Result from the reaction of a metal and a non-metal. Because of the large . electronegativity. difference, electrons transfer from the metallic atom to the non-metallic atom and the ions that result attract each other. . Don’t talk when the teacher is talking. Respect others in the classroom. Ask questions if you are unsure. Complete all homework on time. Atomic structure. KEYWORDS. : Atom, proton, neutron,. electron. Ionic bonds . result when electrons are transferred between atoms. Covalent bonds . result when valence electrons are shared between atoms. Types of Bonds. Formed between a . metal. and a . non-metal. Fall, 2017. 2. X-ray Diffraction Image. Images like these can be used to determine crystal structures. 3. Comparison of Radii. 4. Squashed versus Unsquashed. Left, metallic or covalent radius. Right, Van der Waals radius. Day . 6. – Venn Diagram, . haber. Process. Metallic . Bonding, Properties of Substances reading, . Warm up. ON PAGE 23. What do ionic and covalent bonding have in common? What is different?. Time: . What is the atmosphere?. Dry air is a mixture of gases. Our atmosphere is made up of the following:. 78% Nitrogen. 21% Oxygen. 1% Argon. 0.04% Carbon Dioxide . Chemicals of air consists of atoms and small molecules. There are weak forces of attraction between the molecules so these chemicals have low melting and low boiling points..
