a. It does not adequately predict the ionization energy of the valence electron(s) for elements other than hydrogen. b. It makes no attempt to explain why the negative electron does not eventually fall into the positive nucleus. c. It does not adequately predict the line spectrum of hydrogen. d...On the other hand, there are a number of arguments against the use of nanotechnology. Most of these concerns are over safety regulations. People are concerned that nanotechnology is not only being used to build small computer parts, but that it is also being used in food, clothing and medicine.How Bohr's model of hydrogen explains atomic emission spectra. If you're behind a web filter, please make sure that the domains *.kastatic.org and *.kasandbox.org are unblocked.This video explores Bohr's atomic model and how Bohr used hydrogen's emission spectra to create his model of the atom. The video also looks at the...Bohrs theory satisfactorily explains the spectra of species having one electron, viz. hydrogen atom. It says "The orbits in which electron can revolve are known as stationary orbits because in these orbits energy of electron is always constant." Electrons can revolve only in those orbits whose angular...

THE NANOBOTS!Scientists recently created a microscopic robot that...

It does not adequately predict the ionization energy of the first energy level electrons for one-electron species for elements other than hydrogen. The Bohr type makes astounding prediction - with regard to the scale of the hydrogen atom, valence ranges, and how plenty power is mandatory to get rid of...The model states that the electron can exist only in certain allowed orbits around the proton: those whose radius r satisfies r = n 2 (0.052 9 nm), where n = 1, 2, 3, …. For one of the possible allowed states of the atom, the electric potential energy of the system is −13.6 eV.bohr model of the atom was proposed by neil bohr in 1915. It came into existence with the modification of rutherford's model of an atom. Bohr modified this atomic structure model by explaining that electrons move in fixed orbital's (shells) and not anywhere in between and he also...In the last lesson, you learned that atoms of different elements produce different atomic spectra when they are struck by an electric spark or an electric current. This phenomenon is really rather puzzling. Why do atoms emit light when they are exposed to an electric current?

▸ Principal Component Analysis : Consider the following 2D dataset: Which of the following figures correspond to possible values that PCA may return for (the first eigen vector / first principal component)? Check all that apply (you may have to check more than one figure).An atom is the smallest unit of ordinary matter that forms a chemical element. Every solid, liquid, gas, and plasma is composed of neutral or ionized atoms. Atoms are extremely small, typically around 100 picometers across.It does not adequately predict the ionization energy of the first-energy-level electrons for one-electron species for elements other than hydrogen. d. This is a step by step verification of the answer by our certified expert. Subscribe to our livestream channel for more helpful videos....the Bohr model of the atom? a. It makes no attempt to explain why the negative electron does not eventually fall into the positive nucleus. b. It does not adequately predict the line spectrum of hydrogen. c. It does not adequately predict the ionization energy of the valence electron(s) for elements other.[D] It does not adequately predict the ionization energy of the 1st energy level electrons for one-electron species for elements other than hydrogen. Bohr Model was introduced by Niels Bohr in the year of 1913. He proposes that the atom is very small and has positive nucleus which has electron...

Classical (Newtonian) physics generally is slightly an approximation. that does now not imply it in point of fact is now not smart. The Bohr sort makes astounding prediction - with regard to the scale of the hydrogen atom, valence ranges, and how lots energy is necessary to get rid of an electron. transferring from Bohr's sort to clean up misconceptions is higher than starting up with a quantum type toddlers will perhaps now not have the flexibility to totally grasp shut. id, on the different hand, posits an all efficient "clothier", which predicts something, and therefore explains not something. in walk in the park, any claim which will no longer be capable to be falsified explains now not something. identity isn't generation. besides, according to quantum physics radioactive decay is an uncaused method. which talent it in point of fact is obtainable now not each factor has a reason, and the reasoning used to claim that the universe or lifestyles unavoidably could be ended in is going out the window.
