Question

Do atomic radius and electronegativity have the same trend or opposite trends? Why? Give examples.

Option 1: They have the same trend.
Option 2: They have opposite trends.
Option 3: It depends on the element.

Answer 1

The atomic radius and electronegativity have opposite trends on the periodic table, with the atomic radius generally increasing from top to bottom in a column and electronegativity generally increasing from left to right in a row.

Step-by-step explanation:

The atomic radius and electronegativity have opposite trends on the periodic table. The atomic radius generally increases from top to bottom in a column, while electronegativity generally increases from left to right in a row.

For example, if we compare the halogens (Group 17) on the periodic table, the atomic radius gets larger as we move down the group from fluorine to iodine. However, the electronegativity values for these elements increase from left to right, with fluorine having the highest electronegativity.

Therefore, option 2 (They have opposite trends) is the correct answer.
