However, the hydrogen-1 atom has no neutrons and a positive hydrogen ion has no electrons.

However, physicists distinguish between atomic physics — which deals with the atom as a system consisting of a nucleus and electrons — and nuclear physics, which considers atomic nuclei alone.

However, if the excited atom has been previously ionized, in particular if one of its inner shell electrons has been removed, a phenomenon known as the Auger effect may take place where the quantity of energy is transferred to one of the bound electrons causing it to go into the continuum.

However, the idea that electrons might revolve around a compact nucleus with definite angular momentum was convincingly argued at least 19 years earlier by Niels Bohr, and the Japanese physicist Hantaro Nagaoka published an orbit-based hypothesis for electronic behavior as early as 1904.

However, this did not explain similarities between different atoms, as expressed by the periodic table, such as the fact that helium ( 2 electrons ), neon ( 10 electrons ), and argon ( 18 electrons ) exhibit similar chemical behavior.

These he interpreted as " negative-energy electrons " and attempted to identify them with protons in his 1930 paper A Theory of Electrons and Protons However, these " negative-energy electrons " turned out to be positrons, and not protons.

However, once the applied electric field approaches the breakdown value, free electrons become sufficiently accelerated by the electric field to create additional free electrons by colliding, and ionizing, neutral gas atoms or molecules in a process called avalanche breakdown.

However, metal electrode surfaces can cause a region of the vacuum to become conductive by injecting free electrons or ions through either field electron emission or thermionic emission.

However, as the temperature of a semiconductor rises above absolute zero, there is more energy in the semiconductor to spend on lattice vibration and on exciting electrons into the conduction band.

However, electrons are not easily released from the unheated anode surface when the voltage polarity is reversed.

However, the electrons do not arrive at the screen in any predictable order.

However, it is not clear what should be considered to be valence electrons for the d-and f-block elements, which leads to an ambiguity for their electronegativities calculated by the Allen method.

However, most chemists followed Kekulé's lead in pursuing and developing what some have called " classical " structure theory, which was modified after the discovery of electrons ( 1897 ) and the development of quantum mechanics ( in the 1920s ).

However in materials with a filled electron shell, the total dipole moment of the electrons is zero because the spins are in up / down pairs.

However, this is a specific property of hydrogen and is no longer true for more complicated atoms which have a ( effective ) potential differing from the form 1 / r ( due to the presence of the inner electrons shielding the nucleus potential ).

However, according to quantum physics, individual molecules ( and atoms, electrons, protons etc.

However, the action of the anion accepting the cation's valence electrons and the subsequent attraction of the ions to each other releases energy and thus lowers the overall energy of the system.

However, quantum mechanical effects force electrons to take on discrete positions in orbitals.

However, in paramagnetic and ferromagnetic substances, the diamagnetic effect is overwhelmed by the much stronger effects caused by the unpaired electrons.

However, in addition to the electrons ' intrinsic magnetic moment's tendency to be parallel to an applied field, there is also in these materials a tendency for these magnetic moments to orient parallel to each other to maintain a lowered-energy state.

However, the opposite can also be true-An opponent can turn a positive statement into a bad one, if the speaker uses ambiguity ( intentionally or not ).

However, shortly after this positive result, Kurt Gödel published On Formally Undecidable Propositions of Principia Mathematica and Related Systems ( 1931 ), showing that in any sufficiently strong axiomatic system there are true statements which cannot be proved in the system.

However not all reception of Steinsaltz ' studies have been wholly positive.

However Elizabeth Gaskell, who believed that marriage provided ' clear and defined duties ' that were beneficial for a woman, encouraged Charlotte to consider the positive aspects of such a union, and even tried to use her contacts to engineer an improvement in Nicholls ' financial situation.

However, many of them oppose abortion, as they see it as a positive liberty and violates the non-aggression principle because abortion is aggression towards the fetus.

However, the combined effects of ethnic and religious fractionalization, i. e. the more chance that any two randomly chosen people will be from separate ethnic or religious groups the less chance of a civil war, were also significant and positive, as long as the country avoided ethnic dominance.

However, in general, the state is viewed as a positive location for corporate tax purposes because favorable laws of incorporation allow companies to minimize the corporate expenditures ( achieved through legal standardization of corporate legal processes ), creating a nucleus in Delaware with operating companies often in other states.

" However, despite this positive change, Munch's self-destructive and erratic behavior involved him first with a violent quarrel with another artist, then with an accidental shooting in the presence of Tulla Larsen, who had returned for a brief reconciliation, which injured two of his fingers.

However, these images are still mediated by the same factors as traditional film, such as the “ moving camera, composition, editing, lighting, and all varieties of sound .” While acknowledging the value in inserting positive representations of women in film, some critics asserted that real change would only come about from reconsidering the role of film in society, often from a semiotic point of view.

However, a gerrymander may also be used for purposes that some perceive as positive, such as in US federal voting district boundaries that produce a majority of constituents representative of African-American or other racial minorities ( these are thus called " majority-minority districts ").

However, horror movies do not always present positive endings.

However, it then began to increase again in the late 1980s, encouraged by strong economic performance and an increasingly positive image.

However, any Member State is permitted to maintain previously granted clearances or to add new clearance as granted in other Member States, in the case the EC's Scientific Committee on Food ( SCF ) has given a positive vote for the respective application.

However, in a compromise between the European Parliament and the European Commission, only dried aromatic herbs, spices, and vegetable seasonings can be found in the positive list.

However, reception of the book was not uniformly positive.

However, Coleridge did believe that a dome could be positive if it was connected to religion, but the Khan's dome was one of immoral pleasure and a purposeless life dominated by sensuality and pleasure.

However, anti-MuSK positive patients do not have evidence of thymus pathology.

However, during the years when Mao was China's " Great Helmsman ", a range of positive changes also came to China.

However, this was later cited as a positive feature of the programme's daring scripts in Britain's Best Sitcom by its advocate Rowland Rivron.

However, what one generation may see as positive, later generations may experience negative effects from.

However, these reports are disputed by Leonard D. Jaffe, who was Surveyor program scientist and custodian of the Surveyor 3 parts brought back from the Moon, stated in a letter to the Planetary Society that an unnamed member of his staff reported that a " breach of sterile procedure " took place at just the right time to produce a false positive result.

However, there are indications that staying on one's feet was generally considered a positive thing, while touching the knee ( s ) to the ground or being put to the ground was overall considered disadvantageous.

However, some positive symptoms lack a simple neurotransmitter-based explanation, specifically, the auditory hallucinations observed in schizophrenia.

However the first result is for positive linear functionals, not bounded linear functionals, so the two facts are not equivalent.
