Question

The energy of the second bohr orbit in the hydrogen atom is -3.41 electron volt energy of the second bhor orbit of he+ ion would be

Answer 1

Answer:

-13.6ev

Explanation:

Solution :

Using the formula E=−13.6z2/n2eV Where z is atomic no. And n is the no of orbitSo energy of second orbit of he would be −13.6×2×2/2×2=−13.6eV

Answer 2

Given:

The energy of the second Bohr's orbit in the hydrogen atom = -3.41 eV

To find:

The energy of second Bohr's orbit in a He⁺ ion.

Solution:

• The energy in the nth Bohr's orbit of a single-electron speicy is directly proportional to the square of the atomic number of the speicy (Z²) and inversely proportional to n².
• The atomic number of Helium is 2 and that of hydrogen is 1.
• Therefore, E₂(He⁺) = E₂(H)*2²/1² = -3.41*4 = - 13.64 eV

Answer:

The energy of second Bohr's orbit in a He⁺ ion = -13.64 eV
