Question

The density of Na is higher than K because (A) ionisation potential of Na is greater than K (B) size of Na is smaller than K (C) atomic weight of K is greater than Na (D) only eight electrons are present in third shell of K

Tardigrade Admin · Accepted Answer

The density of Na is higher than K because only eight electrons are present in third shell of potassium while the capacity of third shell is 18 electrons. Further more lower density of K is due to abnormal increase in size of K.
