Question
Which element in each of the following pairs has the larger atomic radius?(a) B or Al (b) P or S (c) Pb or Br
Step 1
This is because with each period, a new electron shell is added, increasing the distance between the nucleus and the outermost electron shell. Therefore, in the pair B (Boron) and Al (Aluminum), Al is below B in the periodic table, hence Al has a larger atomic Show more…
