Generally, the valency of electropositive elements is:

A2, 1, 0
B1, 2, 3
C4, 3, 2
D0, 1, 2
Answer & 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. _Source: RRB Group D CEN-02/2018 PYQ, Q.94._
