Explanation:
according to Bohr's model , electrons revolve around the nucleus in fixed energy orbits
[tex]\bold{Answer\::}[/tex] option 2) [tex]\bold{fixed\:energy\::}[/tex]
[tex]\bold{Additional\: information\::}[/tex]
[tex]\bullet[/tex] according to Bohr's models ,in an atom electron revolve around nucleus in a fixed orbit
[tex]\bullet[/tex] energy of each orbit is fixed
[tex]\bullet[/tex] orbit are numbered from 1 to infinite , n=1 being closet to nucleus .
[tex]\bullet[/tex] radius of orbit increase as we move away from nucleus
[tex]\bullet[/tex] radius of orbit is given by r = (0.53)×(n²/Z) angstrom
[tex]\bullet[/tex] energy of orbit increase as we move to higher orbit
[tex]\bullet[/tex] energy of orbit can be derived by using formula given by E = (-13.6)×([tex]\dfrac{Z^{2} }{n^{2} }[/tex]) { where Z is atomic number , n is number of orbit }
