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.

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.
The scientist who thought the atom was hard solid ball was?
The scientist who first proposed the idea of the atom as a hard solid ball was John Dalton in the early 19th century. Dalton's atomic theory described atoms as tiny, indivisible particles that made up all matter.
What did Democritus originally suggest?
Democritus was an Ancient Greek philosopher who proposed the concept of atoms as the fundamental building blocks of nature. He believed that all matter is made up of tiny indivisible particles called atoms, which he described as eternal, unchangeable, and in constant motion. This idea laid the groundwork for modern atomic theory.
Are solids made of?
ATOMS! Everything is made of atoms, the tiny particles that themselves consist of protons, neutrons and electrons. The reason why things are solid is because of the interactions between different atoms and molecules. These forces are usually attractive. For example, there are electrostatic ionic attractions in a slat crystal, such as NaCl. In a metal, the positive metal nuclei are attracted to a sea of delocalised valence (outer) electrons. These metallic bonds are very strong, which is why metals are very hard solids with high melting/boiling points.
What are particles in a gas are best described as?
Because the particles of the gas are in a state (sometimes called an excitable state) which allows random movement, they are vibrating and continually bouncing against each other, and moving faster if the gas is heated. Smoke rises from a fire because it is heated. Since the hotter particles are hitting their neighbours harder and faster the gas needs to take up more space. It expands. It also becomes lighter or less dense. it begins to rise, forming convection currents. Warm air rises; cold air sinks.
Who discovered that atoms small hard particles?
Democritus

Who stated that all atoms were small hard particles?

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.
The scientist who thought the atom was hard solid ball was?
The scientist who first proposed the idea of the atom as a hard solid ball was John Dalton in the early 19th century. Dalton's atomic theory described atoms as tiny, indivisible particles that made up all matter.
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 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.
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
