What are ions? When atoms gain or lose electrons they become ions This means they are no longer neutral Unit 3: Chemistry. Ions and Ionic Bonding.

Aim: How to distinguish between ionic and covalent bonding? Two major categories of compounds are ionic and molecular (covalent) compounds. Metals tend.

Presentation transcript:

Can you do the following? Determine the Electron and Molecular Geometry Draw a Lewis dot structure Explain the difference between ionic and covalent bonds Write an electron configuration Identify subshells and #of electrons in subshells the number of shells and valance E- the # of electrons from an atom

Electronegativity: the degree to which an element tends to gain electrons and form negative ions in chemical reactions.

Welcome: finish and turn in Lewis Dot Structure worksheet. All parts. A, B and C. Pick up A Model Building Worksheet Do not write on it You need 2 clean pieces of paper Complete procedures 1-5 on your paper, not the worksheet.

Hydrogen = white halogens = green Carbon = black oxygen= red Nitrogen and phosphorus = blue Sulfur= yellow For 5 bonds (or e- pairs) = brown For 6 bonds (or e- pairs) = silver
