Answer 1

Answer:

A ] Vn(Potential Energy) at ground state of hydrogen atom = - 27.2 eV

Kn(Kinetic Energy) at ground state of hydrogen atom = +13.6 eV

Therefore Vn/Kn = - 2

B ] -1

C ] In reality, the lowest orbital angular momentum of an electron in an atom is zero.

D ] rn=0.529n²/Z

So, 1/rn=Z/0.0529n²

and, 1/rnα ∝ Z

Therefore,

Z/0.0529n² ∝ Zy

Comparing the coeffcients of Z, we get y=1
