What else can I help you with?
Small units of matter are called molecules. When they are broken into smaller units what are they called?
When molecules are broken down into smaller units, they are called atoms. Atoms are the basic building blocks of all matter and cannot be further divided into smaller particles without losing their chemical properties.
Describe the discovery that demonstrate for the first time that atoms are not the smallest particles of matter?
The discovery of the subatomic particles demonstrated for the first time that atoms are not the smallest particles of matter. Electron was the first subatomic particle discovered by J.J. Thomson.
Which group cannot be broken down into smaller parts?
Atoms are the smallest units of matter that retain the properties and characteristics of an element. They cannot be broken down into smaller parts without losing their chemical identity.
A false statement concerning matter is Matter cannot be subdivided. Matter is composed of many small particles called atoms. Matter is mostly empty space. All matter contains mass.?
Matter cannot be subdivided is a false statement. Matter can be broken down into smaller particles such as atoms, which are the building blocks of matter.
What do scientists no longer believe about daltons ideas?
Scientists no longer believe in Dalton's idea that atoms are indivisible and are the smallest particles of matter because further research has shown that atoms can be broken down into even smaller subatomic particles like protons, neutrons, and electrons. Additionally, Dalton's notion that all atoms of the same element are identical has been revised with the discovery of isotopes, which are atoms of the same element with different numbers of neutrons.
Are atoms capable of being broken down into smaller particles in a chemical reaction?
Only with fission (see nuclear science).
What is the name of the particles when atoms are broken down?
Quarks
What cannot be broken down into simpler components?
Time and Mass. All particles can be broken down into smaller particles endlessly.
Is an atom indestructable?
No. Atoms can be broken down into subatomic particles.
A substance that cannot be broken down into atoms were?
They are subatomic particles.
Can hydrogen be broken down smaller by a chemical change?
No. Chemical changes can only result in rearranging representative particles (atoms, molecules, formula units.) They can't break down atoms any farther than, well, atoms.
Small units of matter are called molecules. When they are broken into smaller units what are they called?
When molecules are broken down into smaller units, they are called atoms. Atoms are the basic building blocks of all matter and cannot be further divided into smaller particles without losing their chemical properties.
Which of Daltons statements about the atom was later proven false?
less than 100 years ago Dalton published his theory that atoms could not be broken down into smaller particles. Scientist have found out that they can in fact be broken down even further.
Atoms are not subdivided during?
Chemical reactions involve the combination, separation, or rearrangement of atoms. During those processes atoms are not subdivided, created, or destroyed.
What are the simplest substances that can't be broken down?
atoms >> I don't think so, because atoms can be broken down into electron shells, a nucleus, electrons, protons, and neutrons. Those are all very basic particles.
What are the basic particles that make up matter?
The smallest, most basic particles that still have the characteristics of the individual elements (oxygen, gold, carbon, uranium, potassium and many others) are called atoms. An atom of gold is still gold. Once you take any of these atoms apart, you have particles that are common to all elements. The protons in an atom of gold are exactly the same as the protons in an atom of oxygen. The sub-atomic particles, the protons, neutrons and electrons of ordinary atoms, can be broken down into smaller and smaller particles. As we build more and more powerful devices, we find that particles can be broken into smaller and smaller components. I don't believe we yet know where that process will end. This is bringing us to the very limits of what is called particle physics.
How is sand broken down?
The answer sort of depends on whether you are considering elemental particles or composite particles. Composite particles are, by their nature, made up from smaller particles. Example of such particles would be an atom (made up from neutron, protons and electrons), protons (made up from quarks) or even mesons (also made up from quarks). Composite particles can 'break down' into their constituents via interactions; for example in nuclear fission uranium atoms are broken down into smaller atoms. Elementary particles do not consist of smaller particles; they are the elementary building blocks which make up all other particles. As such elementary particles cannot break down into their constituents. Elementary particles can however change into other (multiple) particles via decay. For example a muon can decay into an electron, a muon neutrino and an anti electron neutrino. This does not mean the muon consists of these three particles; other decays are also possible.
