What is the evidence for quarks?
Every particle that should exist if quarks are real has been found. No particle that should not exist if quarks are real has ever been found. The results of in-elastic scattering between hadrons fits perfectly with quark. The hypothesis of charm quarks predicted experimental results that were almost perfectly replicated with the discovery of the psi-particle. In other words, the quark hypothesis matches observation perfectly. That's about as strong of evidence as can exist.
What is a property of protons and electrons?
Protons have a positive charge and they have mass. Electrons have a negative charge and have almost no mas (it is about 1/2000th that of a proton).
What is bigger than a chromosome?
A molecule. elements are a series of atoms that form an element and several elements form a molecule.
The mass of a neutron is nearly equal to the mass of what other subatomic particle?
No, an alpha particle is the nucleus of a normal helium atom - 2 protons + 2 neutrons. Therefore, an alpha particle has approximately 4 times the mass of a proton or neutron.No, an alpha particle is the nucleus of a normal helium atom - 2 protons + 2 neutrons.

What is the smallest part of the atom that has almost no mass?
The smallest part of an atom would be a quark. Quarks are either up or down quarks, and have virtually no mass. Neutrinos have even less mass, but are not part of an atom.
What kind of charge does a neuton have?
Protons, Neutrons, and Electrons are also called "subatomic particles." A neutron is a subatomic particle that has a mass that is ALMOST equal to the mass of a proton. A neutron carries no electric charge; so it is neither positive or negative. It carries a "neutral" charge. So remember, NEUtrons--->NEUtral.
What particle has almost no mass?
The lightest subatomic particle is the electron.
Is there a Simpsons episode called Springfield Elementary School Musical?
Almost, It is simply called Elementary School Musical.
Which of the subatomic particles has a negative charge is found outside of the nucleus and has almost no mass?
The subatomic particle that fits this description is the electron. Electrons have a negative charge, are found outside of the nucleus in electron shells, and have a very small mass compared to protons and neutrons.
What elementary particles have a charge of -1 and mass that is almost zero?
Electrons.
What are some Baltimore City Public Schools?
Baltimore City public schools include Cecil Elementary, Langston Hughes Elementary, and Hilton Elementary. The system serves almost 90,000 students right now.
What is a subatomic particles with almost no mass?
The electron is the lightest particle in the atom.
What two particle's account for almost all of the mass of an atom?
Protons and neutrons.
Where can you buy hamster food?
Almost every pet store out there carries hamster food. I believe even wal-mart carries it.
What river carries almost half of Russia's river traffic?
the Volga river
A pelvic ultrasound carries what risk?
There are no known risks, to either the mother or the fetus, associated with the use of ultrasound.
Can the additive inverse of any rational number negative?
Yes, almost half of them have additive inverses which are negative.
