How do you call a subatomic particle that has no mass and a negative charge?
No such particle exists. All particles with charge also have mass -- no exceptions. Every particle with zero mass also has zero charge -- no exceptions.
A particle that has a mass of 1 and a charge of 1 plus is?
A particle that has a mass of 1 and a charge of 1 plus is a proton.
What are the characteristics of an alpha particle?
An alpha particle has the charge 2+ and the mass 4.
What is the amu of a beta particle?
A beta particle is an electron, this has a mass much less than a proton or neutron and so was can use zero in most situations. However in some calculations for mass defect of whole atoms and Q-value calculations in nuclear decays it can become important, in these calculations. An electron has a mass of 511 keV/(c^2), and an AMU is 931 MeV/(c^2). So, dividing the electron mass by the AMU mass, we get the mass of the beta in AMU: 511/931000 = 0.00055 AMU.
Must a particle have non-zero rest mass in order to have momentum?
Yes. A particle of zero rest mass has ONLY its relativistic mass when in motion. There are actually no photons just sitting around.
What subtomic particle has the same mass as a proton?
Commonly considered to be a neutron. However the true mass of a neutron is slightly higher than the combined mass of a proton and an electron.
Which subatomic particle has such a small mass that is not used to calculate the atoms atomic mass?
electron
Which has the smallest mass?
Hydrogen has the smallest atomic mass at roughly 1.008 grams per mol (6.02x10^23 atoms)
Which particle has the smallest mass atoms or electron?
An electron has a much smaller mass than any atom.
What particle makes up an atoms atomic mass?
the particle that is represent in the mass number is/ sum equals, protons and neutrons.
What two particle's account for almost all of the mass of an atom?
Protons and neutrons.
What is a neutral subatomic particle in an atoms nucleus that has a mass nearly equal to a protons and no change?
Neutrons.
What the smallest particle in a atom?
Size on the scale of atoms is very hard to define. The electron has zero mass. Quarks have varying amounts of mass.
Which particles account for most of the atoms mass?
Physics has not managed to discover a particle that accounts for mass
Which two subatomic particles make up most of the atoms mass Where are they located?
These particle are neutrons and protons; they are located in the atomic nucleus.
What is the relationship between the acceleration of a particle the force that acts on the particle and the mass of the particle?
Acceleration = force/mass
What is the atomic mass-?
The atomic mass is the mass of a molecule, atomic particle or sub-atomic particle.
