Electronic configuration of nitrogen is (2, 5) and that of phosphorous is (2, 8, 5). Nitrogen has two electron shells while phosphorous has three. Since nitrogen has one electron shell less compared to phosphorous, its atomic size is less. Hence, the ten

Over time, each carbon-12 nucleus can take part in a very large number of cycles. A proportion of nitrogen made during the CNO cycle evades further reaction. At the end of a star’s life, this nitrogen may be distributed into the galaxy. In our solar system the nitrogen from a star t...
However, considerable efforts have been made to reduce the cost of metal catalysts and among all the low-cost based metal-catalysts, Ni is the most effective catalyst due to the easy availability of valence shell d-electrons24–30. Experimental and theo- retical studies have been carried out ...
If an atom has an electron in the n = 5 state with m = 3, what are the possible values of l ?Determine the quantum numbers l and m_l for the He^+ ion in the state corresponding to n = 3.What are the possible values of the magnetic qua...
of spinel Co3O4which led to the formation of a geometric configuration unit PO6, triggering electron rearrangement ofcobalt ions. This resulted in the development of highly active Co2+sites on the catalyst surface thereby decreasing the energy barrier of the rate-determining step. The resulting...
Effect of N2gas bubbling, insertion of thioglycolic acid (TGA) and cobalt doping with Co/Zn=x: 0%, 0.1%, 0.3% and 0.5% was studied by means of scanning electron microscopy, transmission electron microscopy, x-ray diffraction, Furrier transformed infrared(FTIR) spectroscopy, UV–Vis ...

Their unique structure makes them conceptually interesting and understanding their formation gives important information on the manipulation and ...
How many neutrons does element x have if it's atomic number is 42 and it's mass number is 154? A certain atom has an atomic mass of 19 and atomic number of 9? How many protons does it have? a) What are electron shells? b) How many electrons are in each? c) How does the num...
increase the availability of energy-yielding electron acceptors and increase N turnover via direct excretion10,11. Thus, macrofauna may alleviate N limitation by priming the remineralization of refractory N, reducing plants-microbe competition12,13. Such activity ultimately promotes N-recycling, plant ...
