Ionic compounds are (usually) formed when a metal reacts with a nonmetal (or a polyatomic ion). What is the name of this compound: S2F10? Introduction to Organic and Biological Chemistry (CHEM120-62398) Uploaded by. Find out more about how we use your information in our Privacy Policy and Cookie Policy. In the case of H+ (Hydrogen) being the cation, the compound is called an acid and when the anion is OH– it is called a base. As mentioned above, Ionic Compounds are a result of electrostatic forces between atoms that get attracted towards each other due to the possession of opposite electrical charges. Covalent compounds occur through the interaction of neutral atoms. Therefore, they group into clusters which are called ‘crystals,’ rather than forming single molecular entities. It is a colorless liquid with a burnt match smell similar to sulfur dioxide. (CC BY-SA 3.0) via Wikimedia Commons, “Covalent” by DynaBlast – Created with Inkscape. In the covalent model the cobalt oxidation state is ignored, and the molecule is not ionic, resulting in 9 electrons total. 2018/2019 If they are both non-metals (such as carbon and oxygen) they will form a covalent … Few examples of ionic compounds are NaCl, MgCl2, etc. 26 terms. Chemistry - Practice Naming Compounds. Sign in-♡Pookie♡-1 decade ago. Covalent Bonds. Named with the prefixes or its common name. In a covalent bond, the atoms are bound by shared electrons. When the involved atoms are similar, the resulting compound is called a ‘di-atomic molecule.’ H2O, CO2, etc. Ionic: CH4: Covalent (NH4)2CO3: Ionic: HCl: Covalent: H2SO4: Covalent: This activity was created by a Quia Web subscriber. Molecular compounds are electrically neutral. In general, atoms that form ionic compounds gets surrounded by the oppositely charged atoms. In the laboratory, S2F10 is prepared by the photochemical reduction of SF5Cl in the presence of hydrogen. Ionic bonds are the strongest type of chemical bond and, therefore, most compounds remain solid with very high melting points. 85 terms. Covalent compounds are formed when two nonmetals react with each other. Mixed Nomenclature Practice Molecular Compounds, Ionic Compounds, & Acids. 85 terms. In this method, both atoms taking part in the formation of the compound get to share the required number of electrons (usually with one donor atom and an acceptor atom looking for the same amount of electrons) in a common overlapped orbital space. Mixed Nomenclature Practice Molecular Compounds, Ionic Compounds, & Acids. Atoms which tend to give away their extra electrons to attain stable electronic configuration end up being positively charged (due to the loss of negatively charged electrons) and these are called, “cations.” Similarly, when atoms accept electrons to complete the final shell configuration they become negatively charged (due to the increase in negatively charged electrons) and these are called, “anions.” Therefore by definition, ionic bonds are formed between anions and cations. Ionic compounds become a good conducting medium in liquid form. Therefore, elements in nature which are not electronically stable, tend to give away any extra electrons or accept the missing number of electrons in order to achieve the closest noble gas configuration. What is the name of this compound: S2F10? As mentioned above, atoms need to form compounds in order to attain a stable electronic configuration. As their names suggest, ionic compounds are made of ionic bonds, and covalent compounds are made of covalent bonds. Using the periodic table, predict whether the following chlorides are ionic or covalent: SiCl 4, PCl 3, CaCl 2, CsCl, CuCl 2, and CrCl 3.
