Hydrogen the simplest of all elements, was investigated most extensively both experimentally and theoretically. As long ago as 1885, Balmer succeeded in obtaining a simple relationship among the wave numbers of the lines in the visible region of the hydrogen spectrum.
The first quantitative correct derivation of the Balmer formula on the basis of an atomic model was given by Bohr (1913), in his theory of the hydrogen atom. Those theory has played such an important role in the development of atomic physics that even though it has been modified and extended by the later developments in quantum mechanics, it will be worthwhile to present the original simplified theory.
In 1913, Niels Bohr proposed a model for the hydrogen atom which retained the earlier nuclear model of Rutherford but made further stipulations as to the behavior of the electron. A dramatic explanation of the Rydberg spectral expression resulted.

The planet Mercury looks like our moon. The surface is covered with craters and has a thick iron core.
it looks like a big circle and have a sign a positively charged
Either 3+ or 2+, depending on which compound it's in (the name of the compound will look like "iron(II) whateverelse" or "iron(III) whateverelse." Hope this helps! :D
So that it can be identified by an enlarged picture
What does diffusion look like? No a picture of what it looks like
Niels Bohr suggested a planetary model for the atom.
Niels Bohr suggested a planetary model for the atom.
bohr model for so2
yes
Niels Bohr created this model; electrons move around the positive atomic nucleus.
The Bohr atomic model is similar to solar system.
I assume you mean Bohr, as in Neils Bohr, the physicist and chemist famous for the Bohr model of the atom.Imagine a "C" inside of a square. If one were to put one "dot" on each side of the hypothetical box, you would have a bohr model Carbon atom.
The electron configuration of platinum is: [Xe]4f145d91.
i dont no but i need to no too. Please tell me if anyone nos
A nucleus, consisting of one proton and one neutron, surrounded by one electron.
Yes, it is true.
nucleus in the middle, 1st energy level has 2, 2nd and 3rd have 8, and 4th has 16
