Science textbooks often represent the atom as a central nucleus composed of protons (+ charged particles) and neutrons (neutral particles) with electrons (- charged particles) orbiting the nucleus. How certain are scientists about the structure of the atom? What specific evidence do you think scientist used to determine what an atom looks like?

The models the scientest use do not provide an absolute understanding of the atom but only a way of abstracting so that they can make useful predictions about them to the best of their ability. The way the structure of the atom was ocncluded was through a set of experiments. They had to go through a trial and error process to develop the current model. the current model is determind by gamma and x-ray spectroscopy. Many additional experiments were performed so they could conferm for sure that this model was the most accurate although many scientest disagree because they say there is no way to actually get a full proof.

Scientist are pretty sure about the physical make-up of the atome. They know the charges and the placement of the protons, neutrons, and electrons. They know the placements of these things because of microscopes and other tools used to see the physical structure of the atom. They also can tell the charges and also the orbitals and electron clouds that the electrons are located.

SCientists are certain about the structure of an atom because intinsive research. scietists as Wilhelm Rontgen and Henri Bccquerel used x-ray like structures to prove the physical appereance of that. Protons, Neutrons, and Electron work together to increase the effiency of job. The positive and negative charges help in the formation of mor complex compounds. Therefore scientists have proven the structure of an atom.

I agree with the first post; the models constucted are simply a moldel that is supported known by physics and the basis of chemistry. The models depicted are not an absolute picture of the aotm, but a model that is constructed by supporting facts already known by scientists.

Scientists do not specifically have any reason to disprove others theory of what an atom, ion, or other subatomic particle may look like. They can simply sculpt models based on physics and realization of the functions that each special part of a atom.

reply to group 1.. i agree with your post. the textbook describes the atom with everything the atom contains. the atom is described in the book using evidence of what they have concluded in their experiments.

RESPONSE TO GROUP THREE POST : I agree with both your post and group 2's response. Although the scientists do not know for one hundered percent sure of the atomic structure. However scientists to have the x-ray machines to tell them the basic structure. Those machines can not give the specific details of the structure though. So they may know the basic structure but the details is what could change.

Excellent! I admire all the helpful data you've shared in your articles. I'm looking forward for more helpful articles from you. :)
