Chemical Bonding SECTION 1 INTRODUCTION TO CHEMICAL BONDING SHORT ANSWER Answer the following questions in the space provided. 1. _____ A chemical bond between atoms results from the attraction between the valence electrons and _____of different atoms. (a) nuclei (c) isotopes (b) inner electrons (d) Lewis structures 2. 1 Bq = 1 event of radiation emission or disintegration per second. One becquerel is an extremely small amount of radioactivity. Commonly used multiples of the Bq unit are kBq (kilobecquerel), MBq (megabecquerel), and GBq (gigabecquerel). 1 kBq = 1000 Bq, 1 MBq = 1000 kBq, 1 GBq = 1000 MBq. The chapters in these volumes are arranged as follows: Chapter 1 (parts 1 to 51), chapter 1 (parts 52 to 99), chapter 2 (parts 201 to 299), chapters 3 to 6, chapters 7 to 14, chapters 15 to 28 and chapter 29 to end. The contents of these volumes represent all current regulations codified under this title of the CFR as of October 1, 2003. Soon after the 1 st International Chemical Congress at Karlsrule in 1860, Cannizzaro's proposal was accepted and a scale of atomic weights was established. To understand how Avogadro's hypothesis can be used to determine relative atomic and molecular masses, visualize two identical boxes with oranges in one and grapes in the other. Name the following chemical compounds: 1) RbBr rubidium bromide 2) Ca 3 (PO 4) 2 calcium phosphate 3) NiF 3 nickle (III) fluoride 4) Sn(NO 3) 4 tin (IV) nitrate 5) Fe(C 2 H 3 O 2) 3 iron (III) acetate 6) K 3 P potassium phosphide 7) N 2 O 3 dinitrogen trioxide 8) Cu(NO 2) 2 copper (II) nitrite 9) P 4 Se 3 tetraphosphorus triselenide 10) (NH 4 ... This activity will allow you to experiment with each of the five types of chemical reactions. You will follow the procedures given below and then write a balanced chemical equation for each reaction. No formal lab report will be due for this lab. Make sure to include detailed observations and a balanced chemical equation for each experiment. 6.1-6.6 Review Worksheet Page 1 of 5 Name_____ 1.
