HW I due next

2. PAd.1: Explain the role of bonding in achieving chemical stability.
6: CHEMICAL BONDING
PAb.3: Explain the trends of the periodic table based on the elements’ valence electrons and atomic numbers.
PAb.5: Predict the charge that a representative element will acquire according to the arrangement of electrons in its outer energy level.
PAd.1: Explain the role of bonding in achieving chemical stability.
PAd.2: Explain how the process of covalent bonding provides chemical stability through the sharing of electrons.
PAd.3: Illustrate the fact that ions attract ions of opposite charge from all directions and form crystal lattices.
PAd.4: Classify compounds as crystalline (containing ionic bonds) or molecular (containing covalent bonds) based on whether their outer electrons are transferred or shared.
PAd.5: Predict the ratio by which the representative elements combine to form binary ionic compounds, and represent that ratio in a chemical formula.

3. You cannot evade the responsibility of tomorrow by evading it today.

Fact: The king of hearts is the only king without a moustache on a standard playing card.

4. VALENCE SHELL Outermost electron shell in an atom
Electrons in this shell are responsible for all chemical reactions

5. ELECTRON DOT STRUCTURE
A model of an atom’s valence shell

6. UNPAIRED ELECTRONS
Single electrons in an energy shell, want a buddy!

7. IONS
Atoms will lose or gain electrons if they have to have a full electron shell (octet)
Loss of e-  positive ion (cation)
Gain of e-  negative ion (anion)

8. ELECTRONEGATIVITY
An atom’s attraction for valence electrons

9. IONIC BONDS
Electric attraction of positive and negative charge

10. COVALENT BONDS Bonds that share electrons, form molecules
Water, diatomics, organic molecules, for example

11. POLAR COVALENT BONDS
Electrons are unevenly shared toward the more electronegative atom

12. COMPARE 3 MAJOR BONDS Ionic Nonpolar covalent Polar covalent
Find an example of each
