6. Using information from the periodic table, predict which two elements would readily combine to make a stable compound. A. HLi B. NaCl C. NaMg D. HeNe
B Sodium (Na) has 1 electron in its outer orbit (one more than empty). Chlorine (Cl) has seven electrons in its outer orbit (one electron short of being "full"). These two elements can combine to make a stable compound, NaCl, with eight electrons in their outer orbits.

Make sure you are thorough in writing down information on categorizing the periodic tableYou will be allowed to use only this sheet on Thursday’s Test ORGANIZATION OF THE PERIODIC TABLE
Organization of Periodic Table • For Thursday’s test you will want to include the following on your periodic table: • NOTE: Do not use the color black *you might color over some important information • Group • Period • Metals • non-metals • Metalloids • Transitional metals • Reactive metals • Halogens • Rare Earth Metals • Noble Gases • Note categories already listed on table: main group elements, transitional metals, inter-transitional metals, etc. • Description of each according to notes
