How many electrons do group 1 elements have on their outer shell
And what does this mean
One electron meaning they are very reactive and have similar properties as eachother
Do group 1 elements have a low or high density
Low density
What is the trend as you go down the group 1 elements (3)
- higher relative atomic mass
- lower melting and boiling points
- increasing reactivity
What ion do group 1 elements form
1+ ions
When group 1 metals are put in water…
They react very vigorously
What gas do g1 elements form when reacted with water
Hydrogen gas
Also hydroxides
As you go down the g1
Reactivity increases
G1 elements react with oxygen to form
Metal oxides
