Honors Chemistry 1 Which of the following is ionic NF 3 HCl CuCl 2 CO 2 2 Which of the following is covalent MgO H 3 N FeO ZnCl 3 To form an ion Nitrogen will Lose 3 electrons to become N. Anions. Cations. Naming Ions. Naming Ionic Compounds. Writing Ionic Formulas. Identify some Anions and . Cations. Anions. Cations. Metals Lose Electrons . (. Cations. = +). Nonmetals tend to gain electrons (Anions = -). 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). Solids. Crystalline Solids- have a regular repeating arrangement of their particles.. Salts, Sugars, Metals. Amorphous Solids- have no regular repeating arrangement of their molecules. Common glass, several polymers.. Hesham. . Alsahafi. . and . Majed. . Almaleky. Robotics, Intelligent Sensing and Control (RISC) Lab . School of Engineering, University of Bridgeport . ABSTRACT. The accumulation of waste has become a major problem in urban city dumps. There are different kinds of waste that affect our environment, for example metallic and plastic waste. Developing metallic waste collection robot system is mighty challenge. There is very limited research related with robot systems that specialize in the collection and processing of waste. In these slides, we propose robotic system that can be used for waste metallic collection. This robot is equipped with metal detector, ultrasonic sensor, control and power unit, and actuators. This autonomous robot can perform tasks such as obstacle avoidance and metal detection. . Endo vs Exo Reaction INQUIRY . Solution Process Model . Solute particle separate (endo).

Right, Van der Waals radius. Chapter 7. An . ion. is an atom that has gained or lost electrons from the valence shell.. Valence electrons. are the electrons contained in the highest occupied energy level. These electrons will mostly determine the chemical properties of the element. SNC2D – Academic Science. Learning Goals. Use . Lewis dot diagrams to illustrate how a compound forms between a metal and a . non-metal.. Ions are formed when electrons are gained or lost. Where do electrons that are lost go?. Metallic Bond – the force that holds metal atoms together. Metals do not form covalent bonds with one another because they do not have enough electrons in their outer shells to form stable octets.. Augustine. Section 7.1 - Ions. Valence electrons. are the electrons in the . highest. occupied energy level.. Valence electrons. are the only electrons involved in . chemical bonding. .. Elements in the same .
