Group 1 - Alkaline metals - chemistry Flashcards
What is the reactivity series of group 1 metals?
It gets more vigorous as you go down the group
What are the 3 properties of alkaline metals?
They are soft metal
The melting and boiling points get lower as you go down the group
They are also less dense
When ionic compounds are made what happens next?
The positive and negative ions are attracted to each other by electrostatic forces of attraction
When alkaline reacts with water what happens?
it reacts vigorously to form metal hydroxide and hydrogen gas
The energy levels increase as you go down the group and it becomes so reactive that it ignites the produced the hydrogen gas
When alkaline reacts with chlorine gas what happens
It reacts vigorously to form a white metal chloride salt
it also gets more vigorous as you go down the reactivity series
when alkaline reacts with oxygen what happens
The alkaline reacts vigorously with oxygen when the oxygen is in a glass jar
The reaction forms white smoke
It reacts vigorously to form metal oxide but the type of oxide produced depends on the type of metal
Why do the group 1 metal get more reactive as you go down the group?
The atomic weight increases as you go down the group
This means that the outermost electron is further away from the positive nucleus
This means the 1 outermost electron can be lost easily making the atom more reactive
