Expert Answer
Esays Student Exploration: Polarity and Intermolecular Forces. A big bully is having a tug-of-war with a small child. There is a ball attached to the middle of the rope. Toward whom will the ball move? Two equally strong kids are having a tug-of-war. What do you expect to happen to the ball in this situation?
Gizmo Warm-up Just like in a tug-of-war, atoms that are bonded to one another pull on the Intermolecular force Essays they share.
In the Polarity and Intermolecular Forces Gizmo, you will explore how these opposing forces relate to bond types and the forces between molecules. To begin, drag the Na sodium and Cl chlorine atoms into the simulation area.

Turn on Show valence electrons. A valence electron is found in the outermost energy level of the atom. Click Play. What do you notice? How do you know? What happens to the colors of the simulated atoms, and what does this indicate? Introduction: A neutral Intermolecular force Essays has the same number of protons as electrons.
Atoms that gain electrons become negatively charged, while those that lose electrons become positive. A polar bond forms when shared electrons are pulled closer to one atom than another, causing the bonded atoms to become partially charged. In a nonpolar bond, electrons are shared equally. Question: What causes bonds to be polar or nonpolar?
Observe: Select the Show polar molecule inset checkbox. The animation shows the probable location of electrons orange http://rmt.edu.pk/nv/custom/analysis-of-paulo-freire-s-the-pedogogy/fredrick-douglass-holidays-the-effect-of-slavery-on-slaves.php in a polar molecule.
What do you notice about the distribution of the electrons? How does this electron distribution affect the charges of the bonded atoms? Observe: Turn on Intermolechlar A. How are the electrons in this molecule distributed? Why do the bonded atoms remain neutral? Experiment: Turn off Intermolecular force Essays polar molecule inset and Show nonpolar molecule inset. Check that Show valence electrons is turned on.

Drag the Na and Cl atoms into the simulation area. Note the colors. Red indicates a negative charge, while blue indicates a positive charge.]
I consider, that you are not right. I suggest it to discuss. Write to me in PM.
I can not take part now in discussion - there is no free time. Very soon I will necessarily express the opinion.
