Isaac Newton
In 1687 Newton published a book Philosophae Naturalis Principia Mathematica.In the book that he published he described universal gravitations and the three laws of motion that was soon talked about for centuries after.
NEWTON’S FIRST LAW DESCRIBES HOW AN OBJECT MOVES WHEN NO FORCE IS ACTING ON ITNEWTON’S SECOND LAW DESCRIBES HOW FORCE AND ACCELERATION ARE RELATEDNEWTON’S THIRD LAW STATES THAT EVERY ACTION HAS AN EQUAL AND OPPOSITE REACTION -
John Dalton
Dalton discovered that certain gases were only able to combine in certain amountsThey could only combine in certain amounts, so even if two different compounds shared the same common element or group of elements. -
Michael Faraday
1821 Faraway published what he had been working on – that being electromagnetic rotation.1831 he discovered electromagnetic induction, this was the principle behind electric transformer and generator. -
Dmitri Mendeleev
The great and wonderful man Dmitri Mendeleev was the original creator of the periodic table.He then used the periodic table of elements that he created to predict the properties of even the elements that were still to be discovered. -
George Johnston Stoney
George Stoney’s most famous work was his conception and calculation of the magnitude of the atom or particle or electricity. Stoney also estimated the number of molecules in a cubic millimetre of gas. -
Joseph John Thomson
In 1912 Joseph Thomson channelled a stream of ionized neon though a magnetic and electric field.In this this he discovered that neon was made of two different types of atoms, this proved the existence of isotopes. -
Niels Henrik David Bohr
Niels Bohr stated that electrons in an atom do not behave the same as the planets do around the sun. The move about the nucleus in a circular orbit at different distances.The more the energy the further the orbit is from the nucleus. There sets of orbits form things called electron shells. There is a limit to the number of electrons that are found in the different shells. -
Ernest Rutherford
Rutherford describes in his atomic theory that an atom has a central positive nucleus and that is surrounded by negative electrons that orbit.The model Rutherford designed suggests that the atom has a small nucleus and that the rest of the atom is mostly empty space.
