Question

What is hydrogen spectrum?​

Answer 1

Answer:

Spectrum emitted when electron jumps from one orbit to another in Hydrogen atom or species having 1 electron.

Explanation:

Emission of energy as spectrum when a electron jumps from one orbit to another.

Answer 2

Spectrum - When a light or radiation is coming from any source and it is passed through a prism than it splits into different wavelengths. These wavelengths are obtained on a photographic plate. And therefore the arrangement obtained on the photographic plate is known as spectrum.

Hydrogen Spectrum - The arrangement produced by hydrogen atom during absorption or emission is known as Hydrogen spectrum.

Total no. lines in spectrum emission

= (n2 - n1)(n1 - 1 + 1) / 2

where

n2 = higher orbit number

n1 = lower orbit number

And

$No. \: of \: lines \: in \\ \: a \: particular \: series \\ = n2 - n1$

where

n1 = lowest orbit number of that series.
