Section 3 Covalent Bonds
______ _____ When atoms ____________one or more electrons______ _____ When atoms ____________one or more electrons Two ____________ share electrons to fill their outermost shell
____________ Two or more atoms joined by a definite ratio.Electron-dot diagrams show the number of ___________ _______
Simplest Molecules _________ ________ made up of two atoms of the same element ___________ ________ elements found naturally as diatomic molecules
Metallic Bonds A bond formed by the attraction between positively charged metal ions and the electrons in the metal.

Chapter 2, Section 2 Combinations of Atoms.
Covalent Bonding. 1/19/12 Objective: To explore multiple covalent bonding Do Now: On a sheet of paper, write the definition of an ionic bond and a covalent.
The Sharing and Transferring of Electrons

Chapter 5: The Structure of Matter Section 1: Ionic Bonds.
Ionic and Covalent Bonding 1. Bonding Atoms with unfilled valence shells are considered unstable. Atoms will try to fill their outer shells by bonding.
Ch. 2: “Chemistry of Life”
Building Blocks 1d Int
How Atoms Combine (7.3). Atoms combine to become more ________. The most stable elements in the periodic table are the ___________________ because they.
Chemical Bonding Chapter 8 Covalent and Metallic Bonds Section 3.
Covalent Bonding In ionic bonding, electrons were transferred to other atoms. In covalent bonding, electrons are shared between atoms. We represent covalent.
IB Honors Chemistry II Cook. You already know how ions are formed by the loss or gain of electrons Covalent bonds are the result of electron sharing.
Covalent bonding results when electrons are shared between non-metal atoms to form a molecule.
Bonding. Bonds Atoms of different elements may join together in a number of ways.
Covalent Bonding Lewis dot structures. Covalent Bonding - Bohr Atoms overlap slightly, and one unpaired electron from each atom will pair together Both.
