Ionic and molecular compounds on line
Start studying ionic vs molecular compounds learn vocabulary, terms, and more with flashcards, games, and other study tools. This page is part of a project to teach high school chemsitry using a website as an integrated in class tool you will find, flash animations, pdf files of labs and. Ionic compounds are formed from strong electrostatic interactions between ions, which result in higher melting points and electrical conductivity compared to covalent compounds covalent compounds have bonds where electrons are shared between atoms. Naming ionic and molecular compounds game name the compounds and win a million.
Name, formula, ionic or molecular, state at rt, solubility, colour of solution, conductivity of solution, melting point, boiling point analysis questions make a generalization about ionic and covalent substances by filling in the following table. A molecule or compound is made when two or more atoms form a chemical bond, linking them togetherthe two types of bonds are ionic bonds and covalent bonds the distinction between them has to do with how equally the atoms participating in the bond share their electrons. Building neutral ionic compounds (ie a student who has one sodium ion and one chloride ion can make sodium chloride) where the number of dots exactly matches the number of holes.
The molecular mass, or molecular weight of a compound (measured in atomic mass units, amu) is obtained by adding up the atomic masses of all of the atoms present within a unit of the substance for ionic compounds, the term formula mass or formula weight is used instead, since there aren't really any molecules present. There are major differences between ionic and covalent bonds ionic bonds consist of metals and nonmetals covalent bonds are made of nothing but nonmetals each bond type follows a distinctive set of nomenclature rules this quiz covers the ability to distinguish between covalent and ionic bonds. A compound is a substance composed of two or more elements combined in a specific ratio and held together by chemical bonds familiar examples of compounds are water and salt (sodium. Ionic and molecular compounds differ primarily in the way they are formed ionic compounds form through the transfer of electrons, while molecular compounds form as a result of electron sharing ionic compounds contain atoms and molecules with opposite charges they bond together as a result of.
This test is designed to measure the understanding of ionic and covalent bonding after they have been given the instructional material test code: 938-g35h for group one of three for the purpose of instruction with section ii review. 42 covalent compounds: formulas and names learning objectives however, polyatomic ions are held together by covalent bonds, so this compound contains both ionic and covalent bonds the elements in n 2 o 4 are both nonmetals, rather than a metal and a nonmetal therefore, the atoms form covalent bonds. Ionic compounds are between metals and non-metals molecular (covalent) compounds are between only non-metals (metallic compounds are between metals and other metals) an ionic compound is a pure. Naming monatomic ions and ionic compounds learn how to name monatomic ions and ionic compounds containing monatomic ions, predict charges for monatomic ions, and understand formulas it is more accurate to think of a continuum between ionic and covalent bonds, and compounds many compounds contain bonds with some fraction of covalent.
Ionic and molecular compounds on line
Ionic compounds form when electrons transfer from one atom to another covalent compounds form when atoms share electrons, resulting in no net loss or gain of electrons as seen in ionic compounds when two or more different chemical elements combine, they form a compound how those atoms combine or. To name a covalent compound, you need the molecular formula, knowledge of the prefixes used for naming, and a way to look up the name of an element given its atomic symbol with this information in hand, you can follow the naming scheme for covalent compounds. Writing & naming formulas of ionic & covalent compounds ©2006 - douglas gilliland the physical science series ionic and covalent structure ionic compounds form a crystalline lattice - a repeating pattern of ions covalent compounds polar covalent compounds have a partial charge at each end of the molecule index 41. It's obvious you've studied how to name ionic compounds and write the formulas from the names you might want to review the rules for naming ionic compounds to make certain you've mastered them the next step is predicting whether two species will form ionic or covalent bonds.
This online quiz is intended to give you extra practice in naming compounds, writing formulas and calculating molar masses (formula weights) select your preferences below and click 'start' to give it a try. The science of molecules is called molecular chemistry or molecular physics, and is the primary interaction occurring in ionic compounds the ions are atoms that have lost one or more electrons (termed cations) and atoms that have gained one or more electrons (termed anions. In the first mission of the ionic and covalent bonds simulation, your task is to choose appropriate laboratory equipment to test the solubility and conductivity of the two substances you will explore how these properties differ in ionic and covalent compounds draw lewis dot structures.
This quiz determines your mastery of ionic compound names and formulas, including the first seven polyatomic ions. Table 41 comparison of ionic and covalent compounds 45 naming binary molecular compounds recall that a molecular formula shows the number of atoms of each element that a molecule contains a molecule of water contains two hydrogen atoms and one oxygen atom, so its formula is h 2 o a molecule of octane, which is a component of gasoline. In chemistry, an ionic compound is a chemical compound composed of ions held together by electrostatic forces termed ionic bonding the compound is neutral overall, but consists of positively charged ions called cations and negatively charged ions called anions.
