The Periodic Table

6 important questions on The Periodic Table

What are the elements in group one called?

Alkali metals

What are the 6 properties of Alkali metals?

Get more reactive as you go down
low density
very soft
shiny but quickly react with oxygen to go dull
Very reactive
Melting and boiling points decrease as you go down.

What happens when Alkali metals react with water?

They produce metal hydroxide + hydrogen

What are the 4 properties of halogens?

They have low melting and boiling points
They boiling points increase as you go down
The reactivity decreases as you go down.
They are poor conductors of heat and electricity

What do they form in reactions to make ionic compounds?

1- charge in their ionic compound with metals

Displacement reactions between halogens

A more reactive halogen will displace a less reactive halogen from solutions of its salts e.g. chlorine will displace bromide ions which form bromine molecules.

The question on the page originate from the summary of the following study material:

  • A unique study and practice tool
  • Never study anything twice again
  • Get the grades you hope for
  • 100% sure, 100% understanding
