1
Q
what are group 1 metals also known by
A
alkali metals
2
Q
name some differences with group 1 elements
A
- lower melting points than most
other metals
.softer than other metals
.have lower densities than other metals
.very reactive
3
Q
what is the common trend in the melting points in group 1 elements
A
the melting points decrease from top to bottom
4
Q
what is the common trend in the boiling points in group 1 elements
A
the boiling points decrease from top to bottom
5
Q
what happens when a group 1 element reacts with water
A
it produces metal hydroxide and hydrogen
the more you go down the group 1 elements, the more violent the reaction with water will become.
6
Q
what happens to the reactivity of alkali metals when you move down the group
A
the get more reactive when you move down, making Lithium the least reactive and Francium the most reactive.
