Plato founded the Atom theory it states that a geometric forms serve as atoms
-
Democritus theory says Atoms are hard, uniform, solid, incomsesible, -
Aristotle's method used information from observations to infer general principles to check against more observation -
Lavoisier's Atomic model was grounded by the law of conservation mass. -
he first part of his theory states that all matter is made of atoms, which are indivisible. The second part of the theory says all atoms of a given element are identical in mass and properties. The third part says compounds are combinations of two or more different types of atoms.
John Dalton's theory says that all mater is made of atoms and that all atoms of a given element are identical in mass -
If elements are put in weight order similar elements will happen after each interval of 8 -
Mendeleev made the periodic table of elements some elements on the table are (H) hydrogen (O) oxygen (C) carbon. -
The photoelectric effect says that electrically charged particles
The photoelectric effect say that electrically charged particles are from or within a material -
the electron is a negative charged particle located in the nucleus -
Radioactivity is the release radiation into the air radiation is danger to humans -
The electron is just outside the nucleus while both the electrons and protons are in the nucleus a electrons has a negative charge while a proton has a positive charge. and neutrons have a neutral charge of zero.
-
A proton holds a positive charge a neutron holds a neutral charge and electrons holds a negative charge. protons were named protons because in Greek pro means first.
-
According to Planck's quantum theory, Different atoms can absorb of emit a certain amount of energy at a time. -
The plum pudding model is a model of a atom with electrons surrounded by positive energy -
A piece of gold is hit with positive charge most particles pass through so gold is mostly empty space -
Robert MIlikan's atomic model showed how scientists can calculate the weight of a electron his discoveries contributed to the modern Atomic model. -
the electrons encircle the nucleus of the atom in a specific way Allowing paths called orbits -
Robert Millikan's discover of element charge says the charge is equal to the charge of the protons minus the number of electrons -
in 1914 Mosley published a paper which atomic numbers are positive charge in the nucleus
-
Schrödinger's equation governs the wave function of a quantum-mechanical system -
The principle of uncertainty states that we cannot know speed and position of a particle like a electron or proton. -
The neutron was first theorized by Ernest Rutherford and discovered in 1932 by James Chadwick.
