Question

group 13 group 14 group 15 group 16 group 17
b - 5 c - 6 n - 7 o - 8 f - 9
al - 13 si - 14 p - 15 s - 16 cl - 17
the table above represents a small piece of the periodic table with each element represented by its symbol and atomic number. which element here has the greatest electronegativity?
your answer should be an element name, symbol or atomic number.

Explanation:

Step1: Recall electronegativity trend

Electronegativity increases across a period (from left to right) and decreases down a group (from top to bottom) in the periodic table.

Step2: Analyze the elements in the table

• Across the periods (rows), we move from Group 13 to Group 17.
• Down the groups (columns), we move from the top row (B, C, N, O, F) to the bottom row (Al, Si, P, S, Cl).

Step3: Identify the rightmost and topmost element

The rightmost group is Group 17, and the topmost element in Group 17 is F (Fluorine) with atomic number 9. Since electronegativity increases across a period and decreases down a group, F is the most electronegative among these elements.

Answer:

F (or Fluorine, or 9)
