(a) Write the ground-state electron configuration for an arsenic atom, showing the number of electrons in each subshell. (b) Give one permissible set of four quantum numbers for each of the outermost electrons in a single As atom when it is in its ground state. ...
Write the ground state electron configuration for an arsenic atom, showing the number of electrons in each subshell (b) Give one permissible set of four quantum numbers for each of the outermost electrons in a single As atom when it is in its ground state. (c) Is an isolated arsenic atom...

Atom (原子)被认为是the smallest part of an element that has the properties of that element,它自身又由proton (质子), neutron (中子)和electron (电子)组成。虽然electron的质量仅为proton or neutron的1/1836,但它在许多方面(e.g. ionisation energy, chemical bond, etc. )发挥重要作用! Electron的强大...

Internal rearrangements of theunpaired electronsof dioxygen result in the formation of two highly reactive species, both known as singlet oxygens (1O2). In 1ΔgO2one unpaired electron is transferred to the orbit of the other (Fig. 24.1), imparting an energy level of 22.4 kcal.mol−1ab...

related to the magnetic spin properties of an atom. The space which is defined by a wave function is termed an Atomic Orbital. An atomic orbital is a region of space where there is a high probability of finding an electron. Principal Quantum Number, n ...
Modifying the reactivity of substrates by encapsulation is essential for microenvironment catalysts. Herein, we report an alternative strategy that modifies the entry behaviour of reactants into the microenvironment and substrate inclusion thermodynamics
