Fill in the best answer for each of the following: a) An ionic bond forms when atoms transfer electrons. b) Another name for an ionic compound is a crystal. c) Instead of forming molecules, ionic compounds form crystals. d) Crystals are 3 dimensional arrays of positive and negative ions in a repeating pattern.
Answer: + that S has a negative 2 charge. There are two "X" ions to balance out the negative 2 charge of S.
Section B: Ionic Bonds ANSWER KEY What is an ionic bond? Atoms will transfer one or more electrons to another to form the bond. Each atom is left with a complete outer shell. An ionic bond forms between a metal ion with a positive charge and a nonmetal ion with a negative charge. Example B1: Sodium + Chlorine Example B2: Magnesium + Iodine

The document tests understanding by having students identify whether example compounds form ionic or covalent bonds based on their constituent atoms and electron configurations. This document contains an answer key for a chemistry worksheet. [1]
Bonding Basics - Ionic Bonds Answer Key/Teacher Notes Complete the chart for each element. Follow your teacher’s directions to complete each ionic bond. (1) Potassium + Fluorine 1- Write the symbols for each element. 2 - Use Fruity Pebbles (or other cereal/candy with more than one color) to create the Lewis structure for each.
Describe the four steps involved in ionic bond formation. An electron (or some electrons) are transferred from a metal atom to a nonmetal atom. The metal atom becomes a positive ion and the nonmetal atom becomes a negative ion. The oppositely charged ions attract each other. An ionic bond is formed. 7. Ions can be positive or negative.
