Groups , reactivity etc Flashcards
What are group 0 elements reactivity as a result of having a fu
ll outer shell?
They are extremely unreactive.
As you go down Group 0
Boiling and melting point increases because the atoms and intermolecular forces become larger.
What is the reactivity of Group 1 elements?
The Group 1 elements are so reactive that they react with oxygen in the air.As a result they must be stored in oil.
Group 7 name?
Halogens
What is the pattern as you go down group 7?
Reactivity decreases
What is the pattern as you go down group 1?
Greater distance between nucleus and outer electrons
Greater shielding of outer electron by inner shell electrons.
