Lab Title: Alkali Metals Reactivity Lab Make-Up
(If you missed the Alkali Metals Demonstrations Done in Class this Make Up Lab is for you.) Write the questions in your lab book then answer them.
Draw Bohr Models for Lithium Sodium and Potassium
What is the same about the 3 Bohr Models?
What is different?
Define Valence electrons
Define Energy Levels
Watch the video pausing it between metals to record your observations in your lab book.
After watching write a periodic law for reactivity of the alkali metals group.
Given the Bohr models, why is potassium more reactive than sodium?
