∙ 10y agoIt was an ancient greek group that believed that atoms exist but they came upon it based on the idea that if you kept cutting a piece of cheese over and over again until you couldn`t anymore there be an atom ( their group name was the atomists) but the size is much much bigger than a real atom. ( oh and they didn`t know about electrons protons and neutrons )

What subatomic particle did the gold foil experiment discover?
Rutherford's gold foil experiment did not discover the existence of any subatomic particles, but it did show the existence of a small, tightly packed, positively charged nucleus and thus led to the discovery of protons.
Are photos made of subatomic particles?
Everything is made of subatomic particles.
When a mineral spontaneously decays into subatomic particles it has this property?
When a mineral spontaneously decays into subatomic particles, it has this property
Which subatomic particles can't change?
All subatomic particles may suffer changes (if you think to "changes", not to "charges").
Is sodium a subatomic particle?
no, its an atom which is broken down into subatomic particles
What observations led scientists to propose the existence of subatomic particles?
Atoms were found to be divisible after all . But scientists discovered that the atoms were made of smller perticles , called subatomic particles.
What is the smallest part of a comet?

What are the Subatomic particles with no charges?

What is in between subatomic particles?
Subatomic particles are: neutron, proton, electron.
Are photos made of subatomic particles?
Everything is made of subatomic particles.
What is A particle not made up of other particles?
subatomic particleIn physics or chemistry, subatomic particles are the small particles composing nucleons and atoms. There are two types of subatomic particles: elementary particles, which are not made of other particles, and composite particles.
How is the existence of the neutrino confirmed?
Actually, we can't even confirm the existence of atoms, let alone subatomic particles. But when scientists conduct experiments, they come to the conclusion that the particles are indeed valid. The more discrete physics becomes, the more theoretical it is.
Subatomic particles bigger than molecles?
subatomic particles make up the molecule
Are subatomic particles found inside atoms?
Yes, atoms contain subatomic particles.
What are molecules and their subatomic particles?
Molecules contain atoms and these atoms contain subatomic particles.
