What happens when lithium reacts with potassium hydroxide?
There will be no reaction between the lithium and the potassium hydroxide. However, since the potassium hydroxide is in solution, the lithium will still react with the water to form lithium hydroxide and hydrogen gas. 2Li + H2O --> H2 + LiOH.
What is true about lithium 6 and lithium 7?
lithium 6 has fewer neutrons, while lithium 7 is heavier
What atom loses its electron easily is it carbon potassium lithium or hydrogen?

What happens when lithium reacts with potassium hydroxide solution?
There will be no reaction between the lithium and the potassium hydroxide. However, since the potassium hydroxide is in solution, the lithium will still react with the water to form lithium hydroxide and hydrogen gas. 2Li + H2O --> H2 + LiOH.
How many outermost electrons do lithium and potassium have?
Both lithium and potassium are in Group I of the Periodic Table, so they both have one valence electron.
What are the family characteristics of sodium?
Potassium and lithium.
