Its atomic mass.
What does the top number(biggest number) on an element represent?
4 of 31
What does the bottom number (smallest number) on an element represent?

5 of 31
Into groups of 3 (triads) with similar properties.
How did Dobereiner order the elements?
6 of 31
How did Newlands order the elements?
In order of relative atomic mass. It only worked for the first 16.
7 of 31
In order of relative atomic mass; recognising the pattern in their properties.
How did Mendeleev order the elements?
8 of 31
Why was Mendeleev's method the best?
He left gaps for missing elements. He predicted missing element's properties. They were then found and he was correct.
9 of 31
Elements to the left of a stepped line between: aluminium & silicon, germanium & arsenic etc are metals.
Which elements are metals?
10 of 31
Which elements are non-metals?
Elements to the right of a stepped line between; aluminium & silicon, germanium & arsenic etc are non-metals.

The alkali metals
What are the group 1 elements called?
12 of 31
What are the group 7 elements called?
The Halogens
13 of 31
Lithium (Li), Sodium (Na). Potassium (K)
Name 3 group 1 metals with their symbols?
14 of 31
Name the 6 properties of Group 1 elements?
Low density: Float on water. Low melting & Boiling points. Shiny when freshly cut. Tarnish quickly in air: react with oxygen. React with water to make Hydrogen and an Alkali Solution. React vigorously with Chlorine Gas to make Chlorides
15 of 31
Sodium (Na(s))+ Water(H2O(l)) = Sodium hydroxide(NaOH(aq)) + Hydrogen(H2(g))
What is the complete reaction of a group 1 element and water?
16 of 31
What is the complete reaction between a group 1 element and chlorine gas?
Sodium (2Na(s)) + Chlorine (Cl2(g)) = Sodium Chloride (2NaCl(s))
