Chemical Bonding

Master chemical bonding! Practice ionic, covalent bonds, and electron dot diagrams.

#1) Why do atoms form compounds? to empty their valence shell to fill their valence shell to have 10 electrons in their valance shell to have 20 electrons in their valence shell #2) Which part of the atom is responsible for bonding? Nucleus Electron cloud Protons Valence electrons #3) Fill in the blank with a NUMBER only. When atoms bonds, they are trying to have 8 valence electrons in their outer shells. #4) Sort the properties of the bonds into "ionic" or "covalent." Ionic atoms gain or lose an electron high conductivity between metals and nonmetals Covalent atoms share electrons low conductivity between nonmetals #5) Which of the following compounds are ionic or covalent? Hints:There are five (5) of each. Ionic LiF NaCl MgO CaCl2 Al2O3 Covalent H2O C3H8O CH4 CO2 NO2 #6) What do bonds look like? Ionic Bond Covalent Bond What is the atomic number of this isotope? 9 6 4 2 How many electrons are in this isotope? 2 4 6 9 What is the mass number of this isotope? 2 4 5 9 How many neutrons are in Chlorine-36? 17 18 19 36 -1 Which electron dot diagram is correct for Fluorine? A B C None of the above How many valence electrons will be in the Electron Dot Diagram for Sulfur? Draw the electron dot diagram for Sulphur.
