Newland + Mendeleev Flashcards
Newlands law on ….
Ovtaves
Newlands put elements in order of …..
Relative Atomic mass
What was the pattern newlands found?
In his order on mass, every every element was similar to the element eight spaces ahead of it
What did newlands table show
A reporting pattern in properties that eventually broke down
Mendeleev published his periodic table in ….
1869
What did Mendeleev do similarly to newlands
Order his elements in relative atomic mass
What did Mendeleev realise in his periodic table?
Physical and chemical properties were related to their atomic mass
Using his realisation how did Mendeleev order his table
He put the elements in order of groups (8) in vertical columns to his table
What was Mendeleev able to predict using his periodic table?
He predicted that the gaps left were undiscovered elements and predict their properties dry to the previous pattern.
What did both scientists do ?
Put them in Oder of mass
What did the scientists do differently?
NL- included only known elements
M- left gaps
NL- maintained a order of atomic weights
M-swapped the order due to properties
NL-every eighth element were similar
M-put them in groups of similarities
