What is the electron configuration of Sr2+? - Socratic
2015年10月17日 · Explanation: Strontium is atomic number 38 so its electron configuration can be written: 2.8.18.8.2. In orbital notation this is: 1s22s22p63s23p63d104s24p65s2. The noble gas shorthand notation is: [Kr]5s2. When strontium forms a 2+ ion the 2 outer 5s electrons are lost so Sr2+ can be written as: 1s22s22p63s23p63d104s24p6.

Why do the electron configurations of chromium and copper
2014年7月7日 · Some elements do not follow the Aufbau principle, there are some alternate ways that electrons can arrange themselves that give these elements better stability. Using the Aufbau principle, you would write the following electron configurations Cr = [Ar] 4s^2 3d^4 Cu = [Ar] 4s^2 3d^9 The actual electron configurations are: Cr = [Ar] 4s^1 3d^5 Cu = [Ar] 4s^1 3d^10 To …
What is the noble gas configuration of strontium? - Answers
The noble gas element strontium (Sr) has the electron configuration of [Kr]5s^2. This means that it has the same electron configuration as krypton (Kr), with two electrons in its outermost shell (5s).
