Question

Which of the following shows three elements in order of decreasing electronegativity?

A)Br, Cl, F

B) F, O, N

C) Se, S, O

D) C, N, O

Answer 1

Answer:

The correct answer is option D which is the decreasing order of conductivity is Mn, O, Ge.

Explanation:

You can easily answer this if you know the periodic trends. For the property of electrical conductivity, it decreases across a period and decreases also down a group. Thus, the most conductive element must be Mn, while the least conductive one is Ge. So, the answer is: -Mn, O, Ge
