Ernest Rutherford determined that with his famous gold foil experiment. Here's what he did: he rigged an alpha particle emitter to shoot alpha particles (made up of 2 protons and 2 neutrons) through a thin piece of gold foil to hit a background where the particles would register their position when they hit. Most of the alpha particles passed clean through the gold foil without touching anything. But a certain small percentage bounced back, and a certain small percentage were deflected. Here's what he determined:
1. atoms are mostly empty space, because most passed clean through.
2. atoms have a nucleus which is tiny, but dense compared with the electron cloud.
3. that nucleus is positively charged, because it deflected the positively charged alpha particles.
This experiment radically changed our view of the structure of an atom, and is one of the most famous experiments ever conducted in science.
What else can I help you with?
What evidence led Rutherford to conclude that an atom is mostly empty space?
The experimental evidence led Rutherford to conclude that an atom is mostly empty space because most of the particles weren't deflected off of the gold foil in his experiment.
Who said matter is made of particles separated by empty space but you have not done any experiments?
Democritus, an ancient Greek philosopher, proposed the idea that matter is made of atoms that are indivisible and separated by empty space. This hypothesis was based on reasoning and philosophical arguments rather than experimental evidence.
What is the homophone for no empty space?
dense
What is empty space compared too?
Empty space is a vacuum.
What is the homophone for a no empty space?
dense
When was Empty Space created?
Empty Spaces was created in 1979.
Is light faster in empty space or in air?
In empty space, ie in a vacuum
Is most of the universe is empty in space?
yes most of the universe is empty space
How The universe is mostly made up of what a. Gases c. Dust b. Empty Space d. Stars?
D: Empty space.
Can travel though empty space?
Yes, you can travel through empty space. The Sun, Earth, moon, satellites, space ships, atoms, and subatomic particles all travel through empty space. Greater than 99.999% of matter is empty space.
Where can light travel but no sound?
Empty space.Empty space.Empty space.Empty space.
What fills the space in between gas molecules Is it just empty space?
The space in between gas molecules is not "just empty space." It is filled with constantly moving and colliding molecules. Gas molecules are in constant motion, so even though there may be more space between them compared to liquids or solids, the space is not truly empty.
