He believed that the 2 principles Mercury and Sulfur formed all metals. He also tried to purify, mature ,certain materials. -
He believed that different types of tiny discrete particles formed all matter. Also, he never got married -
He theorized that indivisible elements shaped like triangle composed solid forms of matter. Also, he was a Greek philosopher. -
Made the idea of atomism, also thought that everything was composed of very tiny particles. He was also born on January 25th 1627 at Lismore Castle. -
He said that matter was conserved during chemical changes which connected to the grounding the law of conservation of mass. He also gave oxygen its name. -
He said that all matter is made of atoms, he also published the first atomic theory. He was known as the father of chemistry. -
The atom would be the ball like structure, as the concepts of atomic nucleus and electrons were unknown at the time. -
He discovered the gas law, today known as Avogadro's law. He also had 6 childern. -
He came up with the the theory that states that elements are arranged from there value of their atomic weight presents a clear periodicity of properties. He was 72 when he died. -
He discovered that atoms were made up of smaller components. He discovered the "electrons " which proposed a model for the structure of the atom. He also won a nobel prize in physics. -
They were a French physicist that discovered radium and powerful radioactive elements ,polonium. Marie Curie was the first female professor at Sorbonne University. -
This model shows how an atom is similar to a plum pudding ,first positive in change (the pudding)with negative electrons (the plums ) scattered through it. -
He mathematically predicted the size of both molecules and atoms. Also, he did not start talking until he was 4. -
He discovered the charge of an individual electron. He also enjoyed playing tennis and golf. -
He described an atom as dense ,tiny, and positively charged core called the nucleus. He was also was the 4th of 12 children. -
This model represents an atom , and they are like tiny solar systems -
Proposed that the hydrogen atom was based on the quantum theory that some physical quantities only take discrete values. Also, the worked on Manhattan project during World War 2. -
He discovered the use of x-rays to study elements and redefine the periodic table. Also, he went to the University of Manchester. -
This shows the area around an atom's nucleus, where electrons are most likely to be found. -
He said that protons and electrons and another subatomic particle called a neutron make up an atom.
