Whoever is doing good weighing dzarrahpun, surely he would see the (return) it. And whosoever does evil by dzarrahpun, surely he would see the (return) it anyway. (Surat al-Zalzalah: 7-8)
a. An element is composed of extremely small particles and can not be subdivided are called atoms. b. All atoms of a particular element have identical characteristics, which distinguish them with atoms of other elements. c. Atoms can not be created, destroyed, or transformed into atoms of other elements. d. Compounds are formed when atoms of different elements combine with each other in a certain ratio. e. The number and types of atoms are constant in a given compound.
atom consists of a positively charged sphere with a uniform charge skyscraper density. In the positive charge is spread electrons with a negative charge equal to the positive charge. A popular way to describe this model is to think of the electrons as raisins (plumb) skyscraper in proton pudding cake, so this model is the model name of raisin cake (plumb-pudding model). skyscraper
Rutherford put a large proton (such as experiments and previous models) in the center of the atom. Rutherford theorized that around protons are big empty spaces of all particles except electrons are sparse.
a. The electrons in an atom move around the nucleus in certain paths, do not radiate energy. Trajectories of electrons is called skyscraper the electron shell or energy level. b. Electrons can move from one track to another track. c. The transfer of electrons from higher energy levels to lower energy emission accompanied. Medium transfer electrons from lower to higher energy levels with the energy absorption. d. Electrons moving on the tracks that are in the stationary state, meaning that electrons do not emit or absorb energy. e. Although the Bohr model of the atom enough to model the spectrum of hydrogen, it has proved insufficient to predict elements of a more complex spectrum.
