Four quantum numbers can be used to completely describe all the attributes of a given electron belonging to an atom, these are: Principal quantum number, denoted by n. Orbital angular momentum quantum number (or azimuthal quantum number), denoted by l. ...
This paper presents the topological index of effective principal quantum number(n*) of AjBk molecules,represented by P defined as P=(n*An*B)-0. 作者定义AjBk分子的有效主量子数拓扑指数(P)为:P=∑(nA·nB)-0。3) quantum topological index 量子拓扑指数 1. A novel quantum topological index...
In an atom, what is the maximum number of electrons that can have a principal quantum number of n = 3? An atom has the following electron configuration: 1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^3 How many valence electrons does this atom have?
How many orbitals in an atom can the designation 3s?How many atomic orbitals are there in a d subshell? What is the maximum value of the secondary quantum number (l) allowed for atomic electrons with a principal quantum number n = 3? In an ...
“Quantum-mechanical model” of electron transfer:In the “quantum-mechanical model”, Lewis (after [74]) claims that contact between nonconductor and conductor leads to the creation of temporary additional donor and/or acceptor states around the contact area. After breaking the contact, the introd...
1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^1 What atom could have the electron configuration of 1s^2 2s^2 2p^3? Write out the electron configuration for Se and then answer the following questions about the last electron added. a. What is the principal qu...
主量子数n是用来描述原子中电子出现几率最大区域离核的远近，或者说它是决定电子层组数的。因为电子排布遵循最低能量原理排布顺序为ns→(n-2)f→(n-1)d→np，故当主量子数等于3时能级排到1s2s2p3s3p4s3d。n相同的电子为一个电子层，电子近乎在同样的空间范围内运动，故称主量子数。主量子数的n的取值为1...
