If an electron jumps from orbit A to orbit B it loses energy while it jumps from C to B it gains energy. Arrange the orbits in the increasing order of distance from the nucleus.

1.	If an electron jumps from orbit A to orbit B it loses energy while it jumps from C to B it gains energy. Arrange the orbits in the increasing order of distance from the nucleus.
Answer» ` A LT B lt C` `C lt A lt B` `C lt B lt A` `A lt C lt B` Solution : When an electron jumps from a higher orbit to a lower orbit it loses energy and vice versa C is K shell NEAR to nucleus B is L shell followed by C A is M shell followed by B `THEREFORE` Increasing order fo distance from the nucleus is `C lt B lt A`
