Question
When Z is doubled in an atom, which of the following statements are consistent with Bohr′s theory?
Options
A.Energy of a state is doubled
B.Radius of an orbit is doubled.
C.Velocity of electron in an orbit is doubled.
D.Energy of a state is halved
Solution
En ∝ Z2 ∴ Z doubled ⇒ En becomes four times.
Rn ∝ 1/Z ∴ Z doubled ⇒ Rn becomes half.
vn ∝ Z ∴ Z doubled ⇒ vn becomes two times.
Rn ∝ 1/Z ∴ Z doubled ⇒ Rn becomes half.
vn ∝ Z ∴ Z doubled ⇒ vn becomes two times.
