NEETChemistryPeriodic Table and PeriodicityMCQ+4 / −1
The correct decreasing order of atomic radii (pm) of and is
- A
- B
- C
- D
View written solutionFree
Correct answer: B
As the atomic number in a period increases, the effective nuclear charge also increases hence, atomic radii along the period decreases.
Correct order of atomic radii
$$\mathrm{Li}>\mathrm{Be}>\mathrm{B}>\mathrm{C}$$
