CHEM 101 Lecture Notes - Lecture 2: Dmitri Mendeleev, Nonmetal, Chemical Bond
Document Summary
Results in a molecule. most common type of chemical bond. Ionic bond-a bond typically between a metal and a nonmetal. Results from a transfer of one or more electrons from one atom to another. Creates oppositely charged ions that group together into large macroscopic lattices, therefore not molecular. Metals tend to give up the electrons, and nonmetals tend to accept the electrons. Ba, rb, sr, li-metals on a periodic table. O, c, h, n, s, br, cl-nonmetals on a periodic table. Element-fundamental substance that can"t be chemically changed or broken down into anything simpler. Dimitri mendeleev-created the forerunner of the modern periodic table in 1869. Gallium-one of the holes in the periodic table contrived by dimitri mendeleev. Was predicted by mendeleev to have a relative mass of 68 and a low melting point. Germanium-one of the holes in the periodic table contrived by dimitri mendeleev.
