Generally, the valency of electropositive elements is:
- 2, 1, 0
- 1, 2, 3
- 4, 3, 2
- 0, 1, 2
Show answer and solution
Correct answer: B. 1, 2, 3
1. Electropositive elements (metals) tend to lose electrons to form positive ions.
2. They commonly lose one, two or three electrons.
3. So their usual valencies are 1, 2 and 3.
