A horizontal row in the periodic table. The two idealized extremes of chemical bonding: (1) ionic bondingin which one or more electrons are transferred completely from one atom to another, and the resulting ions are held together by purely electrostatic forcesand (2) covalent bonding, in which electrons are shared equally between two atoms. Mostly electropositive elements are placed on the left side of the periodic table and the electronegative elements are placed right to the periodic table. The ability of an atom to attract a pair of electrons in a chemical bond is called its electronegativity. Slides 1 - 6 (Atomic . Have a question? The Elements in the Periodic Table are divided into 3 main classes of elements. Explanation: Atoms gain or lose valence electrons to become more stable. The Arrangement of Elements in the Periodic Table - The elements are listed in a series of rows containing elements that have varying chemical properties and columns that have similar chemical properties . The degree to which electrons are shared between atoms varies from completely equal (pure covalent bonding) to not at all (ionic bonding). Alvin W.
