When scientists say that quarks are elementary particles it means that they are NOT made up of other particles.

Are laptons electrons?
I presume you mean lepton instead of lapton ;) In which case leptons are not electrons, but electrons are leptons. Leptons are a group of matter particles which do not feel the strong nuclear force and are believed to be elementary (i.e. they do not consist of smaller particles). They are: -Electron -Muon -Tau(on) -Electron neutrino -Muon neutrino -Tau neutrino and their associated anti particles (such as the anti-electron, commonly known as the positron).
Differentiate between a proton neutron and electron?
A proton has a positive charge, a neutron has NO charge and an electron has a negative charge. All three are spin 1/2 particles and therefore fermions, however, protons and neutrons are each comprised of three elementary particles called quarks, making them baryons, whereas electrons aren't made out of any quarks, making them leptons. The lack of quarks in electrons mean they don't interact with the strong nuclear force, whereas protons and neutrons do. Additionally, protons and neutrons are much more massive, about 2000 times so, than electrons.
What is matter with slow moving particles?
Please clarify what you mean by slow-moving air. Do you mean an air mass that is moving slowly, or a gas particle that is moving slowly? If you mean the latter, perhaps this answers your question: for a given temperature, gas particles with less mass move faster than gas particles with greater mass. Additionally, for a given species, a lower temperature corresponds to lower particle velocity, with absolute zero corresponding to no movement whatsoever.
What does inference mean elementary reading lessons?
It mean to figure something out using your what you all ready know.(Example; a man goes outside and takes out a umbrella- inference is that it is raining outside)Read more: What_does_the_word_inference_means_in_reading
What does it mean when a subatomic particle is in the atom?
Basically, atoms are made up of subatomic particles. Subatomic, sub- meaning smaller that, so subatomic particles means "a particle smaller than an atom". So It means that it is a particle within the atom.
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.
What does the term fundamental mean when referring to particles?
When we apply the term fundamental to particles, we refer to a particle that is not made up of other particles. As an example, an electron is a fundamental particle. It is not made up of other particles, and it is, therefore, a fundamental particle. The proton and neutron, on the other hand, are each made up of three quarks. (The proton has two up quarks and a down quark, while the neutron has two down quarks and an up quark.)
What do you mean by bombarding element?
A nuclear reaction in which an atom is bombarded with elementary particles or with a lighter atom.
What force holds the universe together?
Gluons
What is contained in oxygen?
Up quarks Down quarks Bottom quarks Top Quarks Charm quarks Strange Quarks and then there were leptons... simple- 8 protons 8 electrons 8 Neutrons and if you're dumb and you mean what is in air, then why don't you learn how to google
Why do elecrtons differ in mass from protons and neutons?
Electron is an elementary particle (according to contemporary knowledge, I mean Standard Model), but proton and neutron are not. They both consist of three quarks: neutron - one up, two down quarks, proton - one down, two up ones. But masses of quarks are also not equal to the mass of electron. The reason of that is one of the top question of the nowaday physics.
How can quarks change flavors when they are elementary?
"Elementary" in this context means that they are not known to be made up of smaller particles. It doesn't mean they can't undergo changes. You can think of the flavors as different excitation states of the same particle - comparable to different vibration modes on the same string. In fact, according to string theory (which is not really a scientific theory yet - more a hypothesis), the fundamental structures in the Universe ARE a type of string, and the different vibration modes of those strings are what gives them their different properties.
What is the name of the smallest particles of matter?
If you are talking about "elements" when saying "things" here, it's the atom. The atom is the smallest unit an element can be divided into that retains the chemical properties and physical characteristics of that element. Atoms can be broken down into protons, electrons and neutrons, and these in turn can be broken down further, but this can only be done under special conditions, like by using the big accelerators in a nuclear physics lab.
Does quark have anything to do with energy?
Yes, but not in the sense you probably mean. All particles with a mass ... including quarks ... have an energy equivalent, and there are large amounts of energy associated with the nuclear binding energy, which is related to the strong (color) force that quarks exert on each other. But in the everyday sense of energy like fossil fuels and electricity ... no, not really.
Which is regarded as the universal particle proton or electron?
yes,an electron is a univerrsal constituent of atom because an atom is mainly consist of neutron, proton and electron. proton and electron are in the nucleus where as electrons are around nucleus.
The two particles that are found in the nucleus are?
Assuming you mean the nucleus of an atom, the two particles found are protons and neutrons. Protons carry a positive charge (with a magnitude of +1 elementary charge), while neutrons carry no charge.
