Chemistry · Bohr model of a hydrogen atom: its postulates, derivation of the relations for the energy of the electron and radii of the different orbits, limitations of Bohr's model

An atomic hydrogen is:

An atomic hydrogen is:

  • A. Electrically neutral
  • B. positively charged
  • C. negatively charged
  • D. a free radical with one odd electron

Step-by-step solution

Atomic hydrogen has one proton and one electron. The single electron is unpaired, making it a free radical. While it is electrically neutral (option A is also true), option D is more specific and highlights the characteristic that distinguishes atomic hydrogen from stable species. Options B and C are incorrect as atomic hydrogen has no net charge.
