The electronic configurations are those given by Sidgwick ("Electronic Theory of Valency", 1927). An asterisk marks elements for which the 'normal' atom is thought to have only one electron in the outermost group, but as practically all these give divalent ions, the point is of minor ...
6 The table below shows the electronic configurations of 4 elements V, W, X and Y (not their chemical symbols).Element electronic configuration V2.1W2.7X2.8.8Y2.8.2Which two elements will combine to form a ionic substance? D A Vand X B Vand Y CW and X D Wand Y 相关知识点: 试题...
An atom's stability can be predicted by its electron arrangement. All an atom's orbitals must be occupied for it to be the most stable and unreactive. A most stable electron form also has a fully charged state of energy. Noble gases have a lot of these orbital configurations, which makes...
Which elements have the following electron configurations? [Ar]4s23d8 [Ar]4s23d104p3 [He]2s22p6 [He]2s2 What is the element whose +2 cation has the same electronic configuration as krypton? What element forms an ion with an electronic configuration of 1s^2 2s^2 2p^6 (or Ne) and ...
To simplify the writing of electronic configurations, we can use a shorthand notation that uses the symbol of the previous noble gas in brackets to represent the inner electrons that are in a stable configuration. For example, instead of writing 1s^2 2s^2 2p^6 for neon (Ne), we can writ...
As for the electronic configurations of the elements Co, Zr, Si, and Ge, they are as follows: Co:[Ar] 3d74s2,Zr:[Kr] 4d25s2,Si:[Ne] 3s23p2and Ge:[Ar] 3d104s24p2. In the CoZrSi and CoZrGe alloys, the total count of valence electrons (Zt) is 17. According to the SP rule...
Electronic Configurations: The electronic configurations of the elements are written according to the rules Pauli's, Hund's, and the Aufbau principle. The energy of filling of the orbitals is given by the Aufbau's Principle. Answer and Explanation: In...
To answer the question regarding the basic difference between the electronic configurations of transition and inner-transition elements, we can break down the information into clear steps.1. Define Transition Elements: Trans
