Ch 6.1 Ionic Bonding

Author: deirdre carney
Description:
  • Recognize stable electron configurations
  • Predict an element's properties using number of valence electrons and electron dot diagrams
  • Describe how an ionic bond forms and how ionization energy affects the process
  • Predict the composition of an ionic compound from its chemical formula
  • Relate the properties of ionic compounds to the structure of crystal lattices

Nevada Science Standards

P.12.A.4 Students know atoms bond with one another by transferring or sharing electrons. E/S 

P.12.A.9 Students know the number of electrons in an atom determines whether the atom is electrically neutral or an ion. I/S 

Next Generation Science Standards

HS-PS1-a Evaluate the merits of different atomic and molecular representations based on their ability to explain a given property of matter or phenomenon

HS-PS1-b Use the periodic table as a model to predict the relative properties of elements based on the patterns of electrons in the outer energy levels of atoms

video clip: Introduction to Ionic Bonding

This video is an introduction to ionic bonding, which is one type of chemical bonding. Ionic bonds hold together metal and nonmetal atoms. In ionic bonding, electrons are transferred from a metal atom to a nonmetal atom, creating ions. These ions have opposite charge, so they stick together.

Video clip: Ionic Bonding Part 2

We'll look at the details of ionic bonding, using sodium chloride as an example. Both atoms have unfilled valence shells, which are the outermost energy level. Electrons are transferred from the metal to the nonmetal, creating ions with an opposite charge. The atoms are then held together because of the attraction between the opposite charges
