Question:medium

If the Bohr's radius of H-atom is 52.9 pm and radius of H-like species is 70.53 pm, then chemical species and orbit number are respectively.

Show Hint

Bohr's radius for \( H \)-like species is directly related to the atomic number and the orbit number. For a hydrogen-like ion, the radius decreases as the atomic number increases.
