Periodic Table Flashcards
What are the group 0 gases called
Noble gases
What increases as you go down group 1
Reactivity with water
What happens when Lithium reacts with water
Slow reaction
Gentle bubbling
What happens when sodium reacts with water
Will react violently
Metal will move around the surface quickly
What happens when potassium reacts with water
Hydrogen has lighting a lilac flame because it is an exothermic reaction
What happens when rubidium and caesium react with water
Almost explosive
What has is produced when group 1 metals react with water
Hydrogen
How can we test for hydrogen
Lighted splint
Squeaky pop
What two things decreases down group 1
Melting point and boiling point
What are the group 1 metals called
The alkali metals
Why does the reactivity increase down the group for the alkali metals
Nuclear charge increase
Electrons increase
Shells increase
Atomic radius increases as the inner shells sheild outer electron from nuclear charge
Attraction for outer electron falls so it is loast easier
Why does the melting and boiling points decrease goijg down group 1
The metalic bond gets weaker as the atom gets bigger
How do group 1 metals form ionic compounds
React with non-metals
Which three group 7 non-metals are poisonous
Florine
Chlorine
Bromine
What state is florine and chlorime at room temperature
Gas
