The Periodic Table Flashcards
Where are the transition metals?
Between group 2 and 3
Where are the non metals?
Above a ‘staircase’ going from the bottom of B to the bottoms of At and Rn
What is group 8 known as?
The noble gasses
What is group 7 known as?
The halogens
What are all group 1 elements?
Alkalis
Where are the lanthanides?
Top of the bottom two rows
Where are the actinides?
Bottom of the bottom two rows
What are halogens?
They are elements with atoms one away from a full outer shell so they react aggressively with the alkalis.
What do they produce when reacted with metals?
A range of salts
How are they bonded?
They are simple molecules joined by a single covalent bond
What happens as you go down the column?
The melting and boiling points of halogens increase because the atoms get bigger so their intermolecular forces also get stronger
What happens with displacement and halogens?
A more reactive halogen will displace a less reactive halogen from a solution of one of its compounds
What are the transition metals (properties)
The transition metals are harder, more dense, less reactive and have higher melting and boiling points than group 1. They can form different ions
Why is it useful for them to form different ions?
Different ions produce different coloured compounds and they can be used to catalyse reactions
What are catalysts?
Catalysts speed up chemical reactions
