The atoms in sugar do not form ions; instead, they share their electrons. The type of bond that forms from the sharing of electrons between the atoms of the table sugar is a covalent bond. Table sugar has a much more complex chemical structure than salt. It looks like this: O CH2OH O OH OO H H O HOC OH HO CH2OH H2
Binary (two-element) compounds formed between metals and nonmetals are usually ionic; e.g., NaCl, CaF2, Al2O3, Na3N. The following generalizations help determine the charges on the ions in ionic compounds. 1. Metals form cations; nonmetals form anions. 2. Main-group metals tend to form cations with charges equal to their group number (North

Ionic; Covalent; Description What happens when sugar and salt are added to water? Pour in sugar, shake in salt, and evaporate water to see the effects on concentration and conductivity. Zoom in to see how different sugar and salt compounds dissolve. Zoom in again to explore the role of water. Sample Learning Goals
Ionic compounds like sodium chloride (table salt) and sodium fluoride (found in toothpaste) are held together by ionic bonds; Metallic compounds like gold and aluminum are held together by metallic bonds . Compounds have an identifiable structure based on how their atoms are arranged.
1.2.2 and 1.2.3 define the terms cation and anion and explain, using dot and cross diagrams, how ions are formed and how ionic bonding takes place in simple ionic compounds, limited to elements in Groups 1 (I) and 2 (II) with elements in Groups 6 (VI) …
Worksheet #1 or Worksheet #2 Bond with a classmate activity – an active way to practice bonding and naming binary compounds, each student is an element and has to partner up with another element to create a bond and name the newly formed compound ( blog entry )
