Atomic models.?
Q. This is for 12th grade level chemistry. How does the Bohr model of the atom differ from the Rutherford model? I'm supposed to ask a bunch of people and see which answers are most common and then have some answers that aren't so common at all. And: Which element are the Rutherford and bohr models attempting to represent?

A. Both of them proposed the planetary atomic model, except Bohr's model was an improvement of Rutherford's one. The difference is that Bohr proposed electrons moved in orbits of fixed size and energy, while the movement of electrons in the Rutherford model was unstable.

Unique Science Idea for atomic models?
Q. Well, i have to do this project for science class and i have to make a 3-D model of an atomic model ex. Carbon, oxygen, ect. Please give me a unique idea how to make 1. Thanks!!!
Asked by gata s - Wed Apr 8 19:13:30 2009 - - 1 Answers - 0 Comments

A. Use ping pong balls and poly styrene balls, skewers and glue. Call the ping pong balls 'protons' and 'neutrons' Paint the neutrons red and leave the protons white. Stick these together with the glue - in one big mass. Put the styrene balls on the skewers, ot different distances to show different orbits. Stick these skewers to the model. Have fun.

Asked by Catch 22 - Wed Jan 16 20:50:52 2008 - - 1 Answers - 0 Comments

A. Contribution(?) by Aristotle Aristotle came up with a new theory. He didn't believe in atoms. And everyone knew that Aristotle was a very smart guy, so they believed him. Too bad he was wrong. While the idea of the atom was supported by some later Greek philosophers, it was fiercely attacked by others, including Aristotle, who argued against the existence of such particles. Aristotle : Although the idea of the atom, the smallest, indivisible component of matter, was first proposed in 400 BC, Aristotle didn't like it. He claimed that there was no smallest part of matter and that different substances were made up of proportions of fire, air, earth, and water. As there were of course no experimental means available to test either view,… [cont.]

For making an atomic model of titanium, should I or should I not pair together the electrons?
Q. I am not sure whether or not I should be pairing together the electrons, because I have seen models in which they are paired together.

A. By 'pairing electrons' do you mean like this?: If so then go ahead. It shouldn't matter as long as you have the correct amount of electrons in the right shells.

What experiments did John Dalton conduct to derive his atomic model?
Q. John Dalton came up with the "atomic theory" but I need a general over view about the work which led to this. I need to build upon: "Dalton's theories were based on the idea that atoms of different elements could be distinguished by differences in their weights (established by experimenting with the pressures and weights of different gases). This initial work on gases and his numerous notes thereon demonstrated that the relative weights of various elements follow a numerical and proportionate pattern, which can be naturally arranged in a table" thanks (:
