1

What did Antoine-Laurent de Lavoisier produced

The first modern chemical textbook in which he compiled the first list of elements which he described as 'substances that could not be broken down'

2

What did Antoine-Laurent de Lavoisier devise a theory about

about the formation of compounds from elements which included element O,N,H,P,ZN,S

3

What did Antoine-Laurent de Lavoisier distinguish between

metals and non-metals

4

What did Jaons jakob bezelius do?

> He determined the composition by mass of my compounds
> Responsible for introducing letter - based symbols for elements

5

What did Johann Wolfgang Dobereiner notice?

He noticed that certain groups of three elements ordered by atomic wight would have a element with a weight and properties that were roughly an average of the two other elements

6

What did Johann Wolfgang Dobereiner modify?

he modificed periodic law by putting Tellurium and Iodine in the correct table

7

What did John Newlands devised?

Devised a periodic table that had the elements arranged in order of their relative atomic weight

8

What did John Newlands suggest?

He suggested that rather than being in triads, elements show similar properties to the element eight places after in the table - named this law of octaves

9

What did Dmitri Mendeleev publish?

The modern table

10

How did Dmitri Mendeleev showed element?

ordered by atomic weights and elements were similar properties arranged in vertical columns

11

What did Henry Moseley determine

the atomic number for all the known elements

12

What did moseley modify

mendeleevs periodic law to read that the properties vary periodically with their atomic numbers rather than atomic weights
