Without the neutrally charged neutrons, the protons would mutually repel each other, and the nucleus would fall apart. They are intended to get players thinking about what they already know about elements. According to Bohr (1913), electrons moved in distinctive energy levels or orbitals around the positively charged nucleus of one proton. The Bohr model of carbon contains a nucleus having 6 protons and 6 neutrons in the center, and around this nucleus, there are two electron shells containing 6 electrons. General questions about the properties of elements assume standard temperature and pressure (helium is liquid below -268☌ and gold is a liquid above 1064 ☌). For this game, the most common isotopes of the chemical elements are used. This game presents a simple introduction to the Rutherford-Bohr model of the atom and the way we organize the elements. NS 5.8.2 - Develop an understanding of properties of matter Note: Any bond or intermolecular attraction that can be formed can be broken.Chemical and physical properties of materials can be explained by the structure and arrangement of atoms, ions, and molecules and the forces between them.Matter is made from discrete fundamental units called atoms.Only those shells with a radius provided by the. Bohr’s proposed that electrons orbited the nucleus in specific orbits or shells with a fixed radius. The assumption was the quantization of the structure of atoms. Concepts:Ĭhemical elements, Periodic Table, chemical symbols, atom, atomic number, atomic weight, protons, electrons, neutrons, atomic structure. Bohr Model of the hydrogen atom first proposed the planetary model, but later an assumption concerning the electrons was made. Interactive module that introduces atomic structure Learning objectives:Īfter this activity, the student will be able to describe the basic structure of matter, name the parts of an atom, have experience using the Periodic Table, explain elements, and have the background to understand isotopes.
