What happens to mass in a chemical reaction?
The mass of the products is greater than the mass of the reactants
The mass of the products is lower than the mass of the reactants
The mass of the products is always the same as the mass of the reactants

Recognised similar physical and chemical properties in groups of three elements called 'triads'
Döbereiner
Newlands
Mendeleev
Newton
Put the elements in order of their atomic masses and he showed that every eighth element had similar properties
Döbereiner
Newlands
Mendeleev
Newton
Arranged elements based on their atomic masses and grouped them so that a periodic pattern in their properties could be seen. He also left gaps for undiscovered elements.
