But Niels Bohr looked into this and found out that electrons move in paths around the nucleus. Surprisingly these electron can move from one path to another. They can also jump to a path that is a level above. Bohr created a model called the planetary model. This model shows how the electron move in different energy levels.…

Introduction: According to the Bohr atomic model, electrons orbit the nucleus in fixed paths with specific energies. Each path is therefore often referred to as an “energy level”. Electrons possessing the lowest energy are found in the levels closest to the nucleus. Electrons of higher energy are located in progressively more distant energy levels.…
Dalton atomic model is the simplest model. Atoms only described as a very small ball but massive. This model is still not familiar with the charge within the atom.…
His hypothesis about the charge of the electron being the same as the charge found in hydrogen lined up with this experiment. He formulated the idea that electrons would be found inside an atom, proved that Dalton’s theory about the indivisibility of atoms was wrong. Thomson knew these negatively charged electrons needed to have a positive that would balance them out. A positively charged material would have to surround them and this theory became known as the Plum in the Pudding Theory. The “plums” (negatively charged) were inside the "pudding" (positively charged). From this he drew up one of the first models of an atom [see fig. 1 on p. 8]. His theory was the beginning of explaining chemical bonding and molecular…

John Dalton was an English chemist, physicist, and meteorologist. Dalton was born in 1766. He is best known for his work in color blindness, and of course, his Atomic Theory. His theory gave us an idea about what the universe is really made up of, and he paved the way for many more important scientific discoveries after he died in 1844.…
Niels Bohr applies quantum theory Rutherford’s Atomic Structure by assuming that electrons travel in stationary orbits defined by their angular momentum. This led to the calculation of possible energy levels for these orbits and the postulation that the emission of light occurs when an electron moves into a lower energy orbit.…
