Worked Solution & Example Answer:Which one of the following alternatives lists the atoms of aluminium, calcium, sulfur and chlorine in order of increasing electronegativity? A - VCE - SSCE Chemistry - Question 16 - 2006 - Paper 1
Step 1
Identify the correct order of electronegativity
Answer
To determine the increasing order of electronegativity for the elements involved (aluminium, calcium, sulfur, and chlorine), we can refer to the Pauling scale of electronegativity:
- Calcium (Ca): 1.00 (lowest)
- Aluminium (Al): 1.61
- Sulfur (S): 2.58
- Chlorine (Cl): 3.16 (highest)
Thus, the order from lowest to highest electronegativity is:
Ca < Al < S < Cl
Therefore, the correct choice is B. (lowest) Ca, Al, S, Cl (highest).
