The Periodic Table Flashcards
What group are the alkali metals in?
1
Name 3 metals in group 1
Lithium, Sodium, Potassium
What do alkali metals react to produce?
A metal hydroxide
What happens to the metal oxides as you go down the group?
Density and reactivity increases, but the boiling, melting and softness points decrease
What group are the halogens in?
7
Are halogens metals or non-metals?
Non-metals
Name 3 halognes
Fluorine, Chlorine, Bromine
What happens as you go down the group of halogens?
The boiling and melting points increase, they become darker in colour and become less reactive
What happens when a halogen reacts with a metal?
You get a metal halide
Give 1 use of halogens
