Valence shell electron pair repulsion or VSEPR theory states that the geometry of a molecule or polyatomic ion is determined by the repulsion of pairs of electrons associated with a central atom. The pairs electrons may be bonding or non-bonding (lone pair) electrons. Only valence electrons of the central atom influence the molecular shape. All BUT one assumption listed supports VSEPR theory. Which statement is not critical to supporting VSEPR theory?

A) Opposite charges attract

B) Atoms of elements contain equal numbers of protons and electrons.

C) Pairs of negative electrons in the valence shell of a central atom repel each other.

D) Pairs of electrons tend to occupy positions that minimize repulsions and maximize the distance between them.

Liquefaction was one reason the kobe wharfs were destroyed and other areas nearby. what is liquefaction? a. it is when conditions in the soil send the seismic wave out to the mountains and bounce back b. it is when conditions in the soil change to vigorous p-wave shaking when the surface waves pass by c. it referes to the fact that when an earthquake occurs wet and soft soil will vibrate more vigorously then solid rocky soil strangely in kobe some streets had very bad damage but the next street over had far less damage. what caused this? a. the waves passed through the city hit the mountains and returned back to the city. at some points the incoming and outgoing waves amplified their strength b. the mountains also had a quake and sent waves into the city c. waves hit the moutains and took longer to return
