St. Charles Community College. Ms. . Grobsky. Chemical Bonding. Bonding is the interplay between interactions between atoms. Energetically favored. Electrons on one atom interacting with protons of another atom. Energetically unfavorable. Chemical bond. - attractive force between atoms or ions. Ionic bond . - electrostatic force between oppositely-charges ions; results from the transfer of electrons from a metal to a nonmetal.. Covalent bond . Chapter 8. Concepts of Chemical Bonding.

Bonding models for methane, CH. 4. . Models are NOT reality. Each has its own strengths and limitations.. Ga . Standards. Students know . atoms combine to form molecules by sharing electrons to form covalent or metallic bonds or by exchanging electrons to form ionic bonds.. Malcolm, Xavier, Genna. Octet Rule. -Small molecules and polyatomic ions can use basic octet rule.. -Larger molecules, determine general arrangement of atoms, skeleton.. -Always includes central atom, atoms surrounding it bonded..

Covalent Bonds. Covalent bonds:. occur between two or more . nonmetals. ; electrons are . shared. not transferred (as in ionic bonds). The result of sharing electrons is that atoms attain a more stable electron configuration.. Covalent Bond. bond formed when atoms share electrons.. Examples – . HCl. , H. 2. O, CO. 2. Ionic Bond. bond formed when an atom gains or loses electrons.. Examples – . NaBr. , . NaCl. , . KBr. Types of Chemical Bonds. Ionic bonds. : attraction between positive and negative ions (e- are lost or gained. ). m. etal + nonmetal (K. 2. O). Covalent bonds. : . sharing. of electrons between two .

Section 8.1 – Chemical Bonds, Lewis Symbols, and the Octet Rule. Whenever two atoms or ions are strongly attached to each other, we say there is a chemical bond between them.. There are three general types of chemical bonds: ionic, covalent, and metallic..
