How does reactivity change down Group 1?
Reactivity increases down the group.
Why does reactivity increase down Group 1?
The outer-shell electron is farther from the nucleus and more easily lost. Group 1 reactions depend on losing this electron.
What are the Group 1 elements called?
The alkali metals.
How many outer-shell electrons does a Group 1 atom have?
One.
Why do Group 1 atoms form ions with a +1 charge?
They can relatively easily lose their single outer-shell electron.
Why do Group 1 elements undergo similar types of reactions?
Their chemical behavior depends strongly on their shared one outer-shell electron.
What are the first three alkali metals?
Lithium, sodium and potassium.
What products form when lithium, sodium or potassium reacts with oxygen?
Metal oxides.
What products form when lithium, sodium or potassium reacts with chlorine?
White ionic metal chlorides.
What products form when lithium, sodium or potassium reacts with water?
A metal hydroxide solution and hydrogen gas.
What do the reactions of lithium, sodium and potassium show about the reactivity of Group 1 metals?
Group 1 metals are very reactive.
