ASAP MULTIPLE CHOICE WILL MARK BRAINLIEST What did J. J. Thomson's cathode-ray tube experiment show?

Atoms are small individual spheres.
Electrons are in a cloud surrounding positively charged particles.
Atoms consist of at least some negatively charged particles.
Matter can be neither created nor destroyed.

Atoms consist of at least some negatively charged particles (Electron)

Explanation:

J.J. Thomson's experiments with cathode ray tubes showed that all atoms contain tiny negatively charged subatomic particles or electrons.

Please correct me if I'm wrong.

is has three carbons, so the answer is propylamine.

meth-

eth-

prop-

but-

pent-

hex-

hept-

oct-

non-

explanation:

specific gravity is the density of a substance divided by the density of water. since (at standard temperature and pressure) water has a density of 1 gram/cm3, and since all of the units cancel, specific gravity is usually very close to the same value as density

so "c" is the answer

plz give brainliest
