PPT-Giant covalent structures

What do these images have in common How are they different What do you know about the uses of graphite and carbon Learning questions What are giant covalent molecules How are they similar different from each other. 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. . Chapter 9 ~ most compounds, including those in living organisms, are covalently bonded. What You’ll Learn. I will analyze the nature of a covalent bond. I will name covalently bonded groups of atoms. Examples of Structures. Example 1:. . Metals. are . strong. and . easily shaped. .. Example 2:. . Many substances . form . brittle crystals . which . dissolve. easily in water.. Example 3:. . Diamond. 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). Ball-and-stick model. Molecular . Compounds. OBJECTIVES:. Distinguish. between the melting points and boiling points of . molecular. compounds and . ionic. compounds.. Molecular . Compounds. OBJECTIVES:. . Causeway. Tiia Valli. It is located in County Antrim, on the northeast coast of Northern Ireland, about two miles (3 km) north of the town of . Bushmills. .. . Bushmills. . Distillery. Antrim. The.  . 1) .

Bonding models for methane, CH. 4. . Models are NOT reality. Each has its own strengths and limitations.. Ga . Standards. Students know . atoms combine to form molecules by sharing electrons to form covalent or metallic bonds or by exchanging electrons to form ionic bonds.. 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. Covalent Bonds. Covalent bonds:. occur between two or more . nonmetals. ; electrons are . shared. not transferred (as in ionic bonds). The result of sharing electrons is that atoms attain a more stable electron configuration.. 127 pISSN 2384-1095eISSN 2384-1109 Department of Radiology, Jeju National University Hospital, Jeju-si, KoreaDepartment of Pathology, Jeju National University Hospital, Jeju-si, Korea www.i-mri.org 12 Key . Learning Objectives. • the structure and bonding of diamond and graphite that explain their properties (including heat and electrical conductivity and hardness) and their suitability for diverse applications . covalent. Molecular / simple covalent. Graphite. Diamond. Diagram. of structure. Describe how. the bonds are formed. Melting point & why?. Electrical conductivity & why?. Solubility. & why?.
