Atoms and periodic table unit answer key

Key Ideas Chemists use a unit called the mole to keep track of the number of molecules or atoms in a sample. A mole represents an extremely large number. Scientists use scientific notation to express extremely large or small numbers. The mass (in grams) of one mole of atoms of a substance can be found on the periodic table. Tell the difference between atoms, ions, and isotopes, Describe the differences and similarities between different types of atoms, Explain how models of the structure of the atom have changed over time, Identify features and patterns on the periodic table, and; Correctly use the periodic table to find general information. When atoms of nonmetal elements form ions, they generally gain enough electrons to give them the same number of electrons as an atom of the next noble gas in the periodic table. Atoms of group 17 gain one electron and form anions with a 1− charge; atoms of group 16 gain two electrons and form ions with a 2− charge, and so on.

The Periodic Table Notes: Historical development of the periodic table: Highlights Mendeleev (1869): Put the elements into columns according to their properties. Generally ranked elements by increasing atomic mass. Moseley (1911): Periodic table arranged by atomic number Top table: Metals, nonmetals, and metalloids The periodic table is set up that way, but there is no underlying reason. The quantum model of the atom supports this observation Each element in the column has the same number of valence electrons. Each element in the column has the same ionization energy.
