Question

The correct order of decreasing electronegativity values among the elements I-beryllium, II-oxygen, III-nitrogen and IV-magnesium is
(a) II > III > I > IV
(b) III > IV > II > I
(c) I > II > III > IV
(d) II > III > IV > I

Answer 1

Answer:

2>3>1>4

Explanation:

O2 is more electronegative than n2.

Answer 2

Answer:

The correct answer is option 'a'

*Explanation*

Metals have the lowest electronegativity. So, Mg has the lowest electronegativity. In a period, electronegativity increases. Therefore, oxygen will have highest electronegativity.

So, the decreasing order will be : Oxygen> Nitrogen > Beryllium > Magnesium
