Na, Rb, S, Cl rank the atoms from largest to smallest electronegativity. to rank items as equivalent overlap them.
please someone help me the question?

The correct sequence of electronegativity from largest to smallest are given below.

1) Chlorine (Cl)

2) Sulphur (S)

3) Sodium (Na)

4) Rubidium (Rb)

Explanation:

Value of electronegativity increases when we go from left to right in the periodic table and decrease from top to bottom.

Chlorine is the element of halogen group having higher electronegativity value in the period table. After chlorine, electronegativity value of Sulphur is higher because it belongs to group 6. Then sodium and in the last rubidium which has low value of

electronegativity.
