What are Group 1 metals known as?
Group 1 metals are known as alkali metals
What do alkali metals form when they react with water
Alkali metals form an alkaline solutions when they react with water
Give some examples of Group 1 metals
Lithium, sodium, potassium, rubidium caesium and francium
Where are group 1 metals found in the periodic table?
They are found in the first column of the periodic table
What similar characteristic do all alkali metals share?
Alkali metals each have one electron in their outermost shell
What are some similar characteristic chemical properties alkali metals have?
They are all soft metals which can easily be cut with a knife
They have relatively low densities and low melting points
They are very reactive (they only need to lose one electron to become highly stable)
What is the trend in group 1 metals
the alkali metals are soft and easy to cut, they get softer as you move down the group
What is an exception to the trend?
Potassium is the exception; it has a lower density then sodium
How dense are the first 3 alkali metal’s
The first 3 alkali metals are less than densely
What is their relative melting poin?
They all have relatively low melting points which decrease as you oennhr
