Covalent Bonds

Covalent Bonds. The joy of sharing!. Covalent Bonds. Covalent bonds: occur between two or more nonmetals ; electrons are shared not transferred (as in ionic bonds) The result of sharing electrons is that atoms attain a more stable electron configuration. Covalent Bonds.

Lakeland Intermolecular Forces Review

Lakeland Intermolecular Forces Review. Click on a question to begin. Question 1. Try Again. Strong intermolecular forces lead to high boiling points and low freezing points. Try Again. Correct!. H 2 O has the highest boiling point so it must have the highest intermolecular forces.

Redox Reactions

Redox Reactions. What is it?. Redox Reactions are chemical reactions that involve oxidation and reduction. Oxidation can be defined as a loss of electrons to another substance. Reduction can be defined as an acceptance of electrons from another substance.

Trends in the periodic table

Trends in the periodic table. Atomic radius. Atomic radii trends and explanations. Atomic radius decreases across a period because each successive element has one more proton in its nucleus and one more electron is added to the same valence shell.

Resonance Forms

Resonance Forms. Resonance forms can be compared using the following criteria, beginning with the most important: Has as many octets as possible. Has as many bonds as possible. Has the negative charge on the most electronegative atom. Has as little charge separation as possible.

Electronegativity

Electronegativity. Sometimes the difference in electronegativity between two atoms is so vast (greater than 1.6) that the bonding electrons are fully transferred to the most electronegative atom . Electronegativity.
