Ionic and Covalent Bonding

IONIC BONDING When an atom of a nonmetal takes one or more electrons from an atom of a metal so both atoms end up with eight valence electrons.

Ionic Bonding. What is Ionic Bonding? One type of bonding where valence electrons transfer from: METAL atom to a NONMETAL atom ◦ ONLY VALENCE ELECTRONS.

Chapter Standards: GLE GLE GLE

Ionic Bonding. CA Standards  Students know atoms combine to form molecules by sharing electrons to form covalent or metallic bonds or by exchanging electrons.

Do Now 1.Define electronegativity. 2.What is a bond? 3.What are the THREE types of bonds? 4.What type of bond will form between… Na and Cl?? H and Cl??

bond formed by the giving or Ionic Bond bond formed by the giving or taking of electrons.

Radiesha Vassell.  Bonds are two different atoms that have valance electrons.  They are four different types of bonds… - Ionic ( non metal/metal atoms.

Objectives Know atoms combine to form molecules by sharing electrons to form covalent or metallic bonds or by exchanging electrons to form ionic bonds.

IONIC BONDING. Sodium Atom 11 P 12 N Atomic Number (Z) = 11 Atomic Mass (M) = 23 Protons = 11 Electrons = 11 Neutrons = 12 Na

Chemical Bonds. Cl - Na + Basics to Bonding When atoms join they create a chemical bond. – This chemical bond: is the force that holds two atoms together.

1. Neutron A. The number of protons in an atom. 2. Proton B. Hold the electrons around the nucleus. 3. Electron C. The number of protons plus neutrons.

Positively charged ions and negatively charged ions are attracted to each other and this attraction is the basis of ionic bonding.
