Nitrogen-doped Carbon Quantum Dot Graphitic carbon nitride nanosheets Photocatalytic wastewater treatment rhodamine B 1. Introduction In recent decades, rapid population growth and industrialization have caused widespread water pollution in a variety of sources, including surface water, groundwater, wastewater...
Draw the partial (valence-level) orbital diagram and write the symbol, group number, and period number of the element that is (Ne) 3s23p5. Write the complete orbital diagram for each of the following elements, using boxes to represent orbitals and arrows...
Because of the formation of HBs, most of the water molecules concentrate close to the free electron pair of the nitrogen atom. There are also high concentrations above and below the aromatic ring. When the molecule is excited, part of the charge is transferred from the nitrogen atom to the ...
The electronic configuration is very useful to locate the electrons in a particular orbital of an element. According to Aufbau principle, the electrons will be added to the lowest energy orbitals before higher energy orbitals. We need to consider orbital notation white writing an electronic configurat...
