Question
All elements in the Halogen family react violently because
- Halogens have 1 valence electron that they give away readily to other elements in reactions
- Halogens have 7 valence electrons which gives up massive energy when they give all seven to other elements
- Halogens need only 1 electron which they will violently take from other elements
- Halogens only react violently with water
Hint:
Halogens have 7 electron in their valence shell.
The correct answer is: Halogens need only 1 electron which they will violently take from other elements
- Group 17 is the halogen family.
- It has seven electrons in the valence shell, one less than noble gas configuration.
- Halogens need only one electron, to get that one electron they react vigorously.
