Question
With which element would Calcium most likely bond?
- Nitrogen
- Neon
- Sulfur
- Iodine
Hint:
Calcium forms di-cation and sulfur forms dianion.
The correct answer is: Sulfur
- Calcium group 2 element has 2 electrons in the valence shell, which they tend to lose.
- Sulfur is group 16 element with 6 elements in the valence shell, tend to gain 2 electrons.
- Calcium is most likely to form bond with sulfur.
