# Write Down the Electronic Configuration of the Following Elements from the Given Atomic Numbers. Answer the Following Question with Explanation.7n, 6c, 8o, 5b, 13al Which is the Most Electronegative - Science and Technology 1

Write down the electronic configuration of the following elements from the given atomic numbers. Answer the following question with explanation.

7N, 6C, 8O, 5B, 13Al Which is the most electronegative element among these?

#### Solution

7N, 6C, 8O, 5B, 13Al
Electronic configuration of the following elements is:
7N =2,5
6C = 2,4
8O = 2,6
5B = 2,3
13Al = 2,8,3
8O is the most electronegative element among these because electronegativity increases as we move from left to right in a period of the periodic table.
