Why are some spectral lines brighter then other lines?

If a spectral line is more intense (brighter), it means that more photons corresponding to that wavelength/frequency of light are being emitted or absorbed by the material that's being studied.
(I'm assuming you're talking about absorption or emission spectroscopy, since the word "brighter" implies you're talking about light.)

it would widen slightly for an extraordinarily promptly-rotating gas cloud, via fact that aspects could be Doppler-shifted. you want a *very* speedy rotation to make this measurable, even nonetheless - it rather is many times used to discover how promptly a galaxy rotates, yet for some stars, the rotation is large adequate to be detected.

Simply put, because they bounce off of a denser/heavier nucleus or a different part of the nucleus of an atom.

greater number of electrons==> photonic emissions at similar frequencies for that element/molecule.

they have shorter wave lengths
