group 1 metals Flashcards
What happens when a metal chloride is formed?
The metal chloride is a white solid which dissolves into water forming a solution which is colourless.
When metals react with oxygen what is formed?
Metal oxides
What is formed on the metal when a metal oxide is formed?
Rust is formed on the metal.The metals turns from shiny to having rust on it.
What happens when metals react with water?
Form metal hydroxide and hydrogen
What happens when metals react with water?
There is a release of energy which is enough to melt the metal.
When metals react with water what do they do?
They float on the surface of the water.
They release heat which is used to melt the metal.
What happens to the reactivity as you go down group 1?
The reactivity of metals increase
Why does the reactivity of metas increase?
Due to outer electrons being more easily lost.This is due to weaker attrcation betweeen the nucleus and electrons.
Atomic radius increases.
What is the trend of the melting point as you go down the group?
The melting point decreases as you go down group 1.
What happens to the density as you go dwon group 1?
The density of the metal incraeses as you go down group 1
