Niels Bohr, a Danish physicist, later proposed his famous Planetary model. He stated that the particles orbited the nucleus like how the planets revolve around the sun. He also said that they move in constant motion in the speed of light, and that the electron closest to the nucleus has the lowest energy.
Erwin Schrodinger, another physicist, concluded that the electrons orbited the nucleus in a wavy sort of manner. He stated that electrons were located in specific energy levels and that there is no exact path around the nucleus.
James Chadwick, who was responsible for the discovery of neutrons (neutrally charged particles) proposed his quantum mechanical model. He believed that the protons and neutrons are all grouped together while the electrons orbit them.
Now that’s how great scientists discovered my structure. - I'm made up of positive charges, or Protons, negative charges, or Electrons, and neutral charges, or Neutrons. - Electrons orbit the protons and neutrons, which are all grouped up in the nucleus.
But more information was discovered about me overtime: - The number of protons in an atom is called an atomic number. - Protons and electrons are of equal number if the element is neutral. - Protons + Neutrons = atomic mass. - Neutrons = mass number - atomic number. - Atoms with the same number of protons but with different number of neutrons are called isotopes. - An atom in which the total number of electrons is not equal to the total number of protons is called an ion.
Now there you have it! But you know what? Until now, scientists are continuously researching about me and my brilliant structure. Because you really never know, you might discover more, if you’ll only look closer.
