• 1834-1907• Russian chemist/inventor• Youngest of 17 siblings• Professor• Died from influenza• Crater on Moon

(Mendeleev) and element #101 (mendelevium) named after him

Dmitri Mendeleev

Mendeleev noticed patterns of elements when organized by atomic mass. He was even able to predict properties of elements that haven’t been discovered yet!

Your challenge is to find periodic patterns to design your own periodic table.

2. Support this statement: “Group 2 elements are reactive” using observations from the Mg in vinegar activity and Mg and Heat demonstration.

3. How many electrons are in each magnesium’s outer electron orbital? Will Mg give its electrons away or grab electrons to get a full outermost orbital?

4. Think about your answer to #3. Which group of elements will be most likely to bond with magnesium? Think about how many electrons magnesium will give away. Which group of elements need this many to gain a full outermost orbital?

Mastery Objective: The students will describe the atomic composition of simple molecules by graphing relationships found among periods and groups in the periodic table.

Drill Warm-Up:Identify the following groups:

1. This group includes the lanthanides and actinides. 2. This group has 6 valence electrons and includes only one gas. 3. Which group has a complete outermost orbital? This means these

elements are rarely found combined with other atoms because they are so stable.
