Suppose you have a sample of potassium Describe several ways you could use periodic trends and a knowledge of valence electrons to predict the element's reactiivity and how the element will behave in a chemical bond.

Me i dont know what to do! the table compares the number of electrons in two unknown neutral atoms. comparison of electrons atom number of electrons a 10 d 11 use this information to determine the number of valence electrons in the atoms. which of the following correctly compares the stability of the two atoms? both are unreactive. both are highly reactive. a is unreactive and d is reactive. a is reactive and d is unreactive.

What is the indicator of the number of ions in solution? the amount of conductivity the amount of precipitate the amount of solute added

What are the two major rules associated with polarity
