Here are the essential concepts you must grasp in order to answer the question correctly.
Bohr Model of the Atom
The Bohr model describes the hydrogen atom as having electrons in fixed orbits around the nucleus, with quantized energy levels. Each orbit corresponds to a specific energy state, and the electron can only occupy these discrete levels. The model simplifies the complex behavior of electrons by treating them as particles in circular orbits, allowing for the calculation of properties like angular momentum.

Quantization of Angular Momentum
In the Bohr model, the angular momentum of an electron in orbit is quantized and given by the formula L = nħ, where L is the angular momentum, n is the principal quantum number, and ħ is the reduced Planck's constant. This means that the angular momentum can only take on certain discrete values, which are determined by the integer n. This quantization is fundamental to understanding the stability of electron orbits.

Energy Levels in Hydrogen Atom
The energy levels of a hydrogen atom are defined by the formula E_n = -13.6 eV/n², where E_n is the energy of the nth level. For a given energy state, the principal quantum number n can be determined, which in turn allows for the calculation of the angular momentum. In this case, an energy of -1.51 eV corresponds to a specific value of n, which is essential for finding the angular momentum of the electron.
