The valency of eLements:
A. Decreases as we go down a group
B. Remons same in a group
C. Increases as we go down a group
D. First increases and then decreases as we go down a group
Answer:B
The valency of eLements:
A. Decreases as we go down a group B. Remons same in a group C. Increases as we go down a group D. First increases and then decreases as we go down a group
Explanation: The valency of elements is equal to the number of valence electrons in case of metals and (8 – valence electrons) for non-metals. Moreover, all elements belonging to the same group have same outer shell electronic configuration. Therefore, valency of elements remains same in a group.
