Question

Arrange oxygen, sulfur, calcium, rubidium, and potassium in order of decreasing electronegativity.

Answer 1

oxygen, sulphur, potassium , calcium , rubidium

Answer 2

Decreasing order of given elements according to its electronegativity is Oxygen>Sulphur>Calcium>Potassium>Rubidium.

Explanation:

• The given elements are Oxygen, Sulphur, Calcium, Rubidium, Potassium.

• In the periodic table, the electronegativity keeps on increasing gradually from the left to right and decreases from top to bottom in a group.

• The Oxygen, in the periodic table, is the rightmost element in the given elements, will have the greatest electronegativity and then comes the Sulphur which lies below the Oxygen.

• Then the Calcium which is present at the left side of the table and then comes the Potassium which is left to Calcium and at last comes the Rubidium lies below Potassium.
