he didn't democriths did Dalton did first.
Erwin Schrödinger made significant contributions to quantum mechanics, particularly in developing the Schrödinger equation, which describes how the quantum state of a physical system changes over time. This equation is a fundamental tool in quantum physics and is used to calculate the behavior of quantum systems. Schrödinger's work helped lay the foundation for the modern understanding of quantum theory.
Aristotle did not propose an atomic theory; instead, he rejected the concept of atoms put forth by his predecessor, Democritus. Aristotle believed in the idea of continuous matter rather than discrete particles.
the idea behind rutherfords atomic theory is that the atom has a central positive nucleus and negatively charged electrons, which move in orbits, surround it. most of the atom is made up of empty space. he assumed this theory through a gold-foil experiment about which you can find information on the internet.
Heisenberg's uncertainty principle, which states the limitations in simultaneously measuring a particle's position and momentum accurately, inspired Schrodinger to find a description of particles in terms of waves. This led Schrodinger to develop his wave equation, which describes the behavior of quantum particles in terms of wave functions.
John DaltonA2. Many scientists contributed to our present ideas - they did not (and have not yet) sprung full blown into existence. JJ Thomson et al developed some of the atomic theory, but even today the full concept of quarks and gluons may elude us - perhaps to be embodied in string theory.
He said that If you arrange the elements accoring to their atomic numbers ,Then you will find that every 8th element has similar properties.
you can find electrons by subtract the atomic number and atomic mass.
We can find tin as a metal element. Atomic number of it is 50.
how do you find the atomic number for an element?
the atomic number is the number of protons of an element. The atomic number specifically identifies an element. You can find it on the Periodic Table of Elements.
The Grand Unification Theory used to be called the Unified Field Theory. It is a search for a theoretical/mathematical framework that can account for and unite all the basic forces, and therefore be considered a Theory of Everything. Currently there are 2 important branches of physics which seem to contradict each other. General Relativity which explains the behaviour of big systems and Quantum Mechanics which explains the behaviour of small systems (atomic/sub-atomic.) If you apply the wrong theory for the size of system then predictions from the theory don't match experimental results. (i.e. The theory is wrong!) Many physisists think there is a theory that can adequately explain both of these systems but they haven't found it yet. Einstein spent his last years attempting to find it. He did not. M theory, a development of string theory is currently considered by many to be the best prospect for a Grand Unification Theory.
if you look @ the Periodic Table, you will find the tiny # above the element... that is its atomic #.
