    puzzle made of smaller pieces. After the discovery of the electron and proton as subatomic particles J.J. Thomson had started to discover atomic theory that gave a complete explanation of atomic structure. According to Thomson protons are embedded in the atoms like a water melon and electrons are present in atoms to make the atom electrically neutral. He called this the “plum pudding” model‚ in the model the electrons and protons are uniformly mixed throughout the atom. His discovery of atomic theory

    An ion is an atom or molecule in which the total number of electrons is not equal to the total number of protons‚ giving it a net positive or negative electrical charge. The name was given by physicist Michael Faraday for the substances that allow a current to pass ("go") between electrodes in a solution‚ when an electric field is applied. It is from Greek ιον‚ meaning "going." The word ion also is responsible for electrical current being symbolized by the letter i in chemistry and physics. An anion

    theory of spectra and atomic constitution‚ atomic theory and the description of nature. NEILS BOHR (1885-1962) His model of atom…. Bohar’s model of atom can be described as follows: An atom is made up of three particles-electrons‚ protons and neutrons.  The protons and neutrons are located in a small nucleus at the centre of the atom.  The electrons revolve rapidly round the nucleus in fixed circular paths called energy levels or shells.  There is a limit to the number of electrons which each

    bases in existence‚ but the most useful one is the Bronsted-Lowry definition: An acid is a substance which can behave as a proton (re presented as a hydrogen ion‚ H+) donor. Any substance which contains hydrogen bonded to a more electronegative element can thus behave as an acid: HCl == H+ + Cl- H2SO4 == H+ + HSO4- A base is a substance which can behave as a proton acceptor. Any species which has a lone pair of electrons can thus behave as a base: NH3 + H+ == NH4+ OH- + H+ == H2O 2

    adioisotopes: What Are They and How Are They Made?What are isotopes?The isotopes of an element are all the atoms that have in their nucleus the number of protons (atomic number) corresponding to the chemical behavior of that element. However‚ the isotopes of a single element vary in the number of neutrons in their nuclei. Since they still have the same number of protons‚ all these isotopes of an element have identical chemical behavior. But since they have different numbers of neutrons‚ these isotopes of the
