-
He proposed the 1st atomic model and concept of atoms as invisible and eternal units of matter. -
He founded the Academy of the Institution in the Western world in 387 BC. He also found that ideal geometric forms serve as atoms. -
He demonstrated that matter is made of tiny particles called corpuscles. -
The Alchemists break down the chemical composition of the 5 elements. Time, fire, earth, wind, and water. -
He established the law of conversion of mass. -
This was created by John Dalton. It shows the model of an atom which defines an atom as a ball-like structure This model also describes a type of conservative logic. -
This model illustrates the positions and motion of the planets and moon. -
In 1804 he was a member of the academy of sciences of Turin. He also proposed that equal volumes of gases contain equal numbers of molecules and that elemental gases are composed of 2 atoms. -
He graduated in jurisprudence in 1792. He also proposed a molecular hypothesis which stated that equal volumes of gases at the same temperature and pressure contain the same number of molecules. -
They both discovered polonium and radium in 1898. He also hypothesized that particles cause atoms to break down. -
He developed a table of atomic weights for atoms. -
He was born on January 27th, 1834. He also devised the periodic table of elements. -
He designed and fine-tuned experiments that confirmed the existence of the electron. -
In 1884 he was elected as a fellow of the royal society. He also discovered the electron. -
This is a historical scientific model of the atom. Also known as Thomson's plum pudding model. -
He proved the existence of atoms and molecules through mathematical calculations.. -
He was president of the Royal Society in 1925 and he also discovered that the atom is empty space surrounding a massive nucleus. -
He published a paper in 1913. He also demonstrated that the major properties of an element are determined by the atomic number. -
This man proposed the Bohr Model which is a way of picturing how atoms are built and how the behave. -
This model was created by an Austrian physicist that consisted of a dense nucleus surrounded by a cloud of electrons. -
He was awarded the Nobel prize in 1935 for physics and he also discovered the neutron.
