Use the chemical formulas below and the periodic table, if necessary, to identify the atoms found in the following substances:
C 6 H 12 O 6 – Glucose (a sugar)
C 2 H 5 OH – Ethyl alcohol
Then on the periodic table, locate each element that you identified. Write what you know about each compound. How are these compounds similar to or different from one another? How are these compounds different from the elements that they are composed of? Write your answers in your Science Journal.
Section 1 Electrons and Chemical Bonding Chapter 8
The ions that make up an ionic compound are bonded in a repeating three-dimensional pattern called a crystal lattice. The crystal lattice is built up so that the positive ions are nearest to the negative ions, forming a solid.
Ionic compounds are brittle and highly soluble, with high melting and boiling points.
