Andrew and Matthew

Ello I'm Andrew ond I'm from Dublin, Ireland. It is cold ond wet but nice. I think that the project is a great idea, and a great learning oppertunity.

Hey I'm Matthew and I am from Cario, Egypt. It is hot during the day, but cold at night.

Associates: Your assigned atomic model is: Electron Cloud Model
Andrew's Research:

Erwin Schrödinger built upon the thoughts of Bohr yet took them in a new direction. He developed the probability function for the Hydrogen atom (and a few others). The probability function basically describes a cloud-like region where the electron is likely to be found. It can not say with any certainty, where the electron actually is at any point in time, yet can describe where it ought to be. Clarity through fuzziness, is one way to describe the idea. The model based on this probability equation can best be described as the cloud model. The cloud model represents a sort of history of where the electron has probably been and where it is likely to be going. The red dot in the middle represents the nucleus while the red dot around the outside represents an instance of the electron. Imagine, as the electron moves it leaves a trace of where it was. This collection of traces quickly begins to resemble a cloud. The probable locations of the electron predicted by Schrödinger's equation happen to coincide with the locations specified in Bohr's model.

Every element in the Peroidic Table has something called an emmsion spectrum. This is caused by applying energy of some kind, and letting light pass through it by making a slit which this makes a beam. This beam goes through a glass prisim to put this light into the spectrum. There are levels in this that are called energy states.

The lowest level is at its ground state. This process may cause electrons to lose some or all of there excess energy. Emitting light causes that. But light wileach corresponding to a particular electronic transition within the allowed states.
