Answer:
Increasing order of Electronegativity:
Neon < Aluminum < Sulfur <Oxygen
0 < 1.61 < 2.58 < 3.44
Explanation:
Electronegativity:
Electronegativity is the power of an atom to attract shared pair of electron in a bond.
Trend in Periodic Table:
- Electronegativity increases from left to right along the period
- It decreases from top to bottom in a group of the periodic table.
- But there are some irregularities in the periodic table as group have differently behave, the are the most stable elements in the periodic table.
- Group VIIIA have complete there duplet and octaet of electron in shells.
- Flourin is the most electronegative element in periodic table
- Cs is the less electronegative and most electropositive in the periodic table
- Atomic radii also effect the electronegativity, the greater the size atom smaller the electronegativity and vise versa.
Electronegativity of the following Compounds is
1. Electronegativity of sulfur:
Sulfur is in group 4 and its
EN of Sulfur = 2.58
2. Electronegative of oxygen:
Oxygen is in group VIA and much electronegative than Sulfur.
The EN oxygen = 3.44
3. Electronegative of Neon:
Neon is group VIIIA member and most stable element thats why have it have no data for electronegativity.
The EN of Neon = 0
4. Electronegative of Al:
It is group IIIA member and have less electronegativity
The EN of Aluminum= 1.61
So the Increasing order of electronegativity is
Neon < Aluminum < Sulfur <Oxygen
