Question

Calculate energy of 2nd orbit for hydrogen.​

Answer 1

Answer:

mol^-1`, hence the energy of. The energy of second Bohr orbit of the hydrogen atom is `- 328 k J mol^-1`, hence the energy of fourth Bohr orbit would be.

Answer 2

The energy of the 2nd orbit for H-atom is - 3.41 eV.

• The energy of an electron is directly proportional to $Z^2/n^2$ in Bohr's model of the atom.
• Bohr stated that electrons in atoms do not radiate energy while orbiting the nucleus, instead they exist in a state of constant energy called stationary states.
• The energy Bohr's orbits refer to, is the energy level an electron needs to gain or lose to jump to another orbit.
• This energy is given by, E = -13.6 $Z^2/n^2$ where Z is the atomic number and n is the orbit number. So when we put Z = 1 and n = 2 we get the energy of the 2nd orbit of H-atom, i.e. -3.41 eV.
