What else can I help you with?
Who stated that all atoms were small hard particles?

Did Democritus describe that Atoms are small hard particles?
Yes, Democritus described that atoms are small, indivisible, and indestructible particles that make up all matter. He believed that atoms are constantly moving and combining to form different substances.
Who proposed that all atoms are small hard particles made of a single material formed into different shapes and and sizes?
It is Democritus (440 B.C.) He proposed the idea that all atoms were small, hard particles made of one material and that everything can be broken down until there is nothing left but atoms. Course, this was long ago, so his theory wasn't exactly thorough enough..
What is the generic term for very small loose particles of hard broken rock or minerals?
The generic term for very small loose particles of hard broken rock or minerals is "sediment." These particles are created through the process of erosion, weathering, and deposition.
Why might it be difficult to determine whether or not microscopic particles are alive?
Microscopic particles are so small and hard to see with the human eye that is they are alive their movement would be small making it hard to determine whether they're alive or not.
Will grit dissolve in water?
No, grit will not dissolve in water as it is composed of small, hard particles such as sand or small stones. These particles will remain in the water without breaking down or dissolving.
What are soft particles and how do they differ from other types of particles?
Soft particles are small, flexible particles that can change shape easily. They differ from other types of particles, like hard particles, because they are more deformable and can move more freely in response to external forces.
What did Rutherford's gold-foil experiment help him conclude?
When Rutherford put the gold foil in front of the alpha-particle emitting source, he noticed a few things: 1. Some of the alpha particles passed through the gold foil 2. Some the particles were deflected 3. Some of the particles bounced back Rutherford concluded that an atom is made up of mostly empty space and the actual size of the atom is far smaller than the space it occupies.
What was Democritus theories?
he thought the atom looked like small, hard particles made of single material formed into different shapes. also that atoms always moving and that they form different materials by joining together. he contributed by having his idea particles always moving.
Who described atoms that they are small hard particles?
John Dalton. N.B.: John Dalton [born: September 6, 1776; died: July 27, 1844, at age 67] was an English chemist and physicist who claimed matter was made up of tiny particles and that these particles were identical for any given kind of matter. Moreover, he claimed these particles were indivisible and could neither be created nor destroyed in any chemical process, only be altered in the manner they were grouped.
What are the three parts of the kinetic theory of matter?
- All matter in composed of atoms and molecules (tiny particles) - The tiny particles are always in motion - Energy affects this motion -The particles interact -There is much space between these particles
Is a atom small and hard?
The original Greeks thought of an atom was that it was a small hard chunk of the matter that it represented, not necessarily ball shaped. As atomic theory developed the models built to represent compounds often used sticks (or springs) and balls to represent the atoms and their bonds. These days an atom is thought to be mostly not there at all. A very small nucleus occupies the center made up of quarks which are hard to describe in physical terms, with an electron density cloud around it showing where the electron might be at any given time. So yes, the atoms are small. And no, they are not hard, at least not hard like a marble.
