到了Cu由于马上3d就要满了，于是4s的一个电子又被抢走了，变成了3d10 4s1。 这是因为 洪特定则的附加规则，半满或者全满更加稳定。 第五周期（32）：5s2，4d10，5p6。 （这里有4d2 5s2—4d4 5s1—4d5 5s1—4d5 5s2—4d7 5s1—4d8 5s1-4d10） 第六周期（32）：6s2，4f14，5d10，6p6（这时已经出现f了，而f的这14个元素被归类为 镧系元素，第七周期 锕系元素 同理，镧系元素和锕系元素在周期表统称为 f区）。 这里已经比较乱了吧，Ce …

How to find the valence electrons of a chosen element? You can check it immediately in our valence electron calculator on the left or look at the position of a particular atom on the periodic table, which will help you to determine how many valence electrons a neutral atom of …

2020年12月19日 · The element denoted by the electron configuration [Kr] 5s2 4d10 5p3 is Antimony (Sb). This is because the total number of electrons (51) equals the atomic number of Antimony in the Periodic table. Explanation: The electron configuration here is [Kr] 5s2 4d10 5p3.

2024年5月29日 · The element with the electron configuration Kr 5s2 4d10 5p5 is iodine, which has 53 electrons in total. The electron configuration indicates that iodine has 7 valence electrons in its outermost...

2024年10月3日 · The tin electron configuration, represented as 5s2 4d10 5p2 or 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d10 5p2, illustrates the precise arrangement of electrons

2017年10月23日 · The ground state electron configuration of a neutral silver atom is [Kr] 5s1 4d10 instead of [Kr] 5s2 4d9. This observation can be explained (theoretically) by the fact that...

2015年12月20日 · In this case, you're looking for an element located after krypton, "Kr". This is confirmed by the fact that the highest-energy electrons are located on the fifth energy level, n = color (red) (5). More specifically, this element will have its highest-energy electrons located in a …

Study with Quizlet and memorize flashcards containing terms like 1. Which element has the following electron configuration? [Kr]5s2 4d10 5p3, 2. Write down the electron configuration of a ground state Ca., 3. Write down the electron configuration of a ground state Ca2+ and more.

2025年3月3日 · The electron configuration Kr 5s2 4d10 5p5 is not valid. This configuration violates the Aufbau principle, which states that electrons fill orbitals starting with the lowest energy levels first.

碘的电子构型为 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d¹⁰ 4p⁶ 5s²4d¹⁰ 5p⁵。 碘，也称为碘，被定义为属于元素周期表的化学元素。 它位于第 17 族，更准确地说是卤素，其原子序数为 53，用符号 I 表示。 这种元素可以分子形式的双原子碘的形式找到。 这种微量元素主要用于摄影、医药和染料。 在其化学形式中，碘是最不活泼的卤素并且是电负性的。 与任何卤素一样，碘会产生双原子分子，从而形成分子式 I2 的碘。 这种元素是在 1811 年发现的，更准确地说是在海藻的灰烬中发现的。 它于 1 …
