-
Greek philosopher who thought that you can’t continuously cut something in half because you will eventually end up with a atom.
He Created the word Atom. -
-
Learned that elements combine in certain proportions based the mass to form a compound.
-
British chemist and school teacher who wanted to know why elements combine in certain proportions.
He stated that elements combine at a certain proportion because their single elements.
all substances are made of atoms.
Atoms of the same element are exactly alike and atoms of different elements are different.
Atoms join with each other to make new substances. -
He stated that there are smaller particles inside atoms and that atoms can be divided.
He experimented with a cathode ray tube and discovered that Positive charged plated can bend and attract a beam.
Electrons = negatively charged particles.
He knows there are electrons but don't know where the electrons are.
Guesses its like a pudding. -
Student of Thompson tested out his teachers theory.
He designed an experiment using a beam of small laser,positively charged particles and aimed it at a sheet of gold.
Rutherford used thompson's idea that atoms are soft like “blobs” and electrons are evenly distributed.
nucleus = in the centre of an atom,very dense and positively charged.
He made a new model that stated that atoms are empty spaced with a tiny nucleus in the middle. -
He was a danish scientist that worked with rutherford.
He Studied of atoms react to light.
He said that electrons move around the nucleus in define paths.
There are no paths in his model as the electrons jump from one path to another.
Atoms have ladders which are said to be said as ladders. -
They stated the electrons don't move in define tracts.
There are regions and the regions are called electron clouds.
