2015年6月14日 · Use the element blocks of the periodic table to find the highest electron orbital. Alternatively, remember group 1 (alkali metals) and group 2 (alkaline earth metals) are s-block, groups 2 through 12 are the d-block, 13 to 18 are the p-block, and the two rows at the bottom of the table (the lanthanides and actinides) are f-block.

For each atom the subshells are given first in concise form, then with all subshells written out, followed by the number of electrons per shell. For phosphorus (element 15) as an example, the concise form is [Ne] 3s 2 3p 3.

电子层 1s、2s、2p、3s、3p是什么东西啊？ 在同一电子层中，电子的能量有微小的差别，而且云的形状也不同。 根据这些差别，一个电子层被分成几个子层。

(a) The element with electron configuration: 1s 2 2s 2 2p 6 3s 2 3p 5; (b)A noble gases with f electrons; (c) a fifth-period element whose atoms have three unpaired p electrons; (d) First row transition metals having one 4s electron.

Typically, you need at least 8 steps to determine the electron configuration, starting with finding the atomic number by looking at the list of orbitals and understanding the notation. We can now see that each electron has a unique "address" in the atom.

实际上分子轨道1σ和2σ上的电子仍在原有的 原子 核周围，本质还是氮原子和氧原子上的K层（n=1）电子，故NO分子的电子构型又可写为KK (3σ)2(4σ)2(1π)4(5σ)2(2π)1。 配合物 的电子构型指中心原子的价电子数。 例：IrCl [P (CH3)3]3中的Ir是16电子的构型，而IrCl3[P (CH3)3]3中的Ir是18电子的构型。 又称电子组态。 是原子、离子或分子的电子状态的一种标志。 按照量子力学的轨道近似法，原子、离子或分子中的每一个电子被认为各处于某自旋和轨道的状态。 体系 …

For example, the electron configuration of the neon atom is 1s2 2s2 2p6, meaning that the 1s, 2s, and 2p subshells are occupied by two, two, and six electrons, respectively. Electronic configurations describe each electron as moving independently in an orbital, in an average field created by the nuclei and all the other electrons.

2024年12月3日 · 氪（Kr）的基态原子电子排布为1s 2 2s 2 2p 6 3s 2 3p 6 3d 10 4s 2 4p 6 。 以上是1至36号元素的基态原子电子排布式，可以看出，元素的电子排布遵循一定的规律，从氢到氪，元素的电子排布逐渐增加，直到达到一个完整的电子层，然后再开始新的电子层。

The K shell contains a 1s subshell hence it can carry 2 electrons, the L shell has 2s and 2p, and can carry 8 electrons. The M shell contains 3s, 3p, and 3d, and can carry 18 electrons. The N shell containing 4s, 4d, 4p and 4f, can carry 32 electrons.
