Question

arrange the elements in increasing order of their the electronegativity such as sodium sulphur aluminium potassium of electronic configuration. give reason

​

Answer 1

Answer:

sulphur>aluminium>sodium>potassium

Explanation:

on going down the periodic table the electro negativity of elements decreases and moving from left to right the electro negativity increases

Answer 2

sulphur>alumunium>sodium>potassium is the increasing order of electronegativity because of their relative positions in the periodic table.

Explanation:

Electronegativity is the property of elements to attract or share their valance electrons. The lesser the number of electrons in the valence shell makes the element ready to donate the electron.

Electronegativity increase from left to right in the periodic table as the number of valence electrons increases.

Electronegativity decrease from top to down in the periodic table due to the increase in distance of valence electron and nucleus ie atomic radii increases.

Potassium is placed down in periodic table to all the elements mention hence least electronegative.

Sulphur with atomic number 16 has 2,8,6 ie 6 electrons in its outer shell

aluminum with atomic number 13 ie 2,8,3

sodium with atomic number 11 has 2, 8,1

We can see that sodium, aluminum, sulphur are placed from left to right.
