SCIENCE STARTER
• PICK UP A SCIENCE STARTER• YOU HAVE 3 MINUTES• YOU ARE SEATED AND SILENT

RESTATE/ASSERT
• Sodium (Na) in the Alka Metal Group ______________ to form chemical reactions with chlorine (Cl) in the Halogen Group

CITE• According to the Periodic Table, both Sodium (Na) and
Chlorine (Cl) are located in Period __________. However, since Sodium (Na) is in Group _________and has only _____________ valence electrons while Chlorine (Cl) is located in Group __________ and has _______________ valence electrons, Sodium (Na) has a _______________ atomic radius than Chlorine (Cl). In addition, due to the number of valence electrons and the atomic radius size, Sodium (Na) will also have a ____________ first ionization energy than Chlorine (Cl) and also Sodium (Na) will have a _______________ electronegativity than Chlorine.

EXPLAIN
• As a result, since Sodium (Na) has a _______________ atomic radius and ______________ first ionization energy/electronegativity than Chlorine (Cl), in a chemical reaction the _________________ electrons in ________________ will want to move away and bond with _____________________.

WINTER ORNAMENT
• Create a winter ornament• Must include at least 8 sections– 4 of them will list the elements and their
properties.• One from each of the 4 major groups• Include the following facts
– Element Name and symbol– Atomic Number– Group Name and Number– Period – No. of Valence electrons – No of energy levels
– 4 of them will be decorative and colorful
