Chose the atom in each pair that has the greater electronegativity.Use correct capitalization to write the correct element in the blankBr or Cl

To determine which atom has the greater electronegativity between Br and Cl, we can refer to the periodic table. Electronegativity generally increases from left to right across a period and decreases from top to bottom within a group.

In this case, Br represents the element bromine, and Cl represents the element chlorine. Both bromine and chlorine are halogens, which are located in Group 17 (Group VIIA) of the periodic table.

Comparing their positions in the periodic table, we can see that chlorine (Cl) is located to the left of bromine (Br). Since electronegativity generally increases from left to right across a period, chlorine has a greater electronegativity than bromine.

Therefore, the atom with the greater electronegativity in this pair is chlorine (Cl).
