4. Make a rule: Based on your data, how are elements arranged into chemical families? 5. Infer: Look at your periodic table. How many valence electrons would you find for elements
in each family?
Boron family:
Carbon family:
Neon family:
6. Think and discuss: How do you think the number of valence electrons relates to an
element's chemical properties?

Achemistry student needs to standardize a fresh solution of sodium hydroxide. he carefully weighs out of oxalic acid , a diprotic acid that can be purchased inexpensively in high purity, and dissolves it in of distilled water. the student then titrates the oxalic acid solution with his sodium hydroxide solution. when the titration reaches the equivalence point, the student finds he has used of sodium hydroxide solution.calculate the molarity of the student's sodium hydroxide solution. be sure your answer has the correct number of significant digits.

Write the chemical formula for a compound that is made of an element from group 1 and an element from group 17
