Group 1 Flashcards
Why do group 1 metals have similar chemical properties
because they have one electron on their outer shell
What physical properties do group 1 metals have in common
low melting points and boiling points
very soft
What bonds do alkali metals form
ionic
How do alkali metals get more reactive
as you go down the group, boiling and melting points decrease
What do you get when you react an alkali metal with water
metal+water=metal hydroxide+water
How does lithium react with water
move in surface, fiercely bubbles
How does sodium react with water
melts into a ball and fizzes on surface
How does potassium react with water
bursts into flames on surface
Why do halogens have similar chemical properties
7 electrons in outcer shell
What do halogens exist as
diatomic molecules
What bonds do halogens usually make
covalent
What happenes as you go down group 7
melting and boiling points increase, reactivity decearses
