Q1 FREE PREVIEW

The incorrect decreasing order of atomic radii is:

Memory Based Question 28/Jan/25 Morning shift

a

\(\mathrm{Si}>\mathrm{P}>\mathrm{Cl}>\mathrm{F}\)

b

\(\mathrm{Mg}>\mathrm{Al}>\mathrm{C}>\mathrm{O}\)

c

\(\mathrm{Al}>\mathrm{B}>\mathrm{N}>\mathrm{F}\)

d

\(\mathrm{Be}>\mathrm{Mg}>\mathrm{Al}>\mathrm{Si}\)

✓ Correct answer: d)

\(\mathrm{Be}>\mathrm{Mg}>\mathrm{Al}>\mathrm{Si}\)

Explanation

Atomic radius is directly related to the size of the atom and the number of shells. it is inversely proportional to the effective nuclear charge. When we move down the group atomic radius increases and across the period atomic radius decreases. Hence, the incorrect order of radii Be >Mg > Al >Si
