Brainlisttt asap! what scientific discoveries led to changes in dalton's atomic theory?

Hey,

Thomson's experiments with cathode ray tubes helped hi discover the electron,
Which Dalton didn't know about.

Dalton also thought that particles were indivisible which was also proved wrong by Thomson when he discovered the existence of subatomic particles.

Hope this helps!

The answer is atmosphere. there are four spheres of the earth: 1. geosphere (from greek word 'geo' = ground), 2. hydrosphere (from greek word 'hydro' = water), 3. biosphere (from greek word 'bio' = life), and 4. atmosphere (from greek word 'atmo' = air). a magnetosphere is a region of space around astronomical objects controlled by the magnetic field of that object. through the process of elimination, since lightning is present in the air, it can be found in the atmosphere.
