Work Step by Step
Okay, let's determine the electron configurations for the most stable ions formed by the given elements: Te, Cl, Sr, and Li.
1. Tellurium (Te):
The most stable ion formed by tellurium is Te^2- (telluride ion).
Electron configuration of Te^2-:
[Kr] 4d^10 5s^2 5p^6
2. Chlorine (Cl):
The most stable ion formed by chlorine is Cl- (chloride ion).
Electron configuration of Cl-:
[Ne] 3s^2 3p^6
3. Strontium (Sr):
The most stable ion formed by strontium is Sr^2+ (strontium ion).
Electron configuration of Sr^2+:
[Kr]
4. Lithium (Li):
The most stable ion formed by lithium is Li+ (lithium ion).
Electron configuration of Li+:
[He]
