MCQ
Orbits in which electrons move according to Bohr are:
  • A
    Elliptical
  • B
    Cylindrical
  • Circular
  • D
    Oval

Answer

Correct option: C.
Circular

First electron shell which is closest to the orbit to the nucleus, called the $1s$ orbit can hold up two two electrons. This orbit is equivalent to the innermost electron shell of the Bhor model of atom. It is called the orbital because it is spherical around the nucleus.
