Paper 1 Bonding, Structure And Properties Of Matter Flashcards
1
Q
When John Newlands put together the periodic table how many elements were there?
A
63
2
Q
What are elements in group 0 known as?
A
Noble gases
3
Q
What outer shell do the noble gases have and what does this mean for their electron configuration?
A
A full outer shell which means they have a very stable electron configuration
4
Q
What are elements in group 1 known as?
A
Alkali metals
5
Q
What are the alkali metals properties?
A
Have one electron in outer shell
Have low melting points and the further down the group the lower the boiling point
More reactive down the group
6
Q
What are alkali metals stored under and why is this?
A
Oil
This is because they react vigorously with oxygen and water
7
Q
What do alkali metals react with and what does this form?
A
Non-metals to form ionic compounds
