The neutral particle of an atom weighing approximately one atomic mass unit?
This atomic particle is the neutron.
Which atomic particle has no mass?
Photons and neutrinos dont have mass.
Can you use the atomic number and atomic mass to calculate the number of each subatomic particle?
atomic number = number of protons = number of electrons atomic mass = mass of protons + mass of neutrons
What happens to atomic number and atomic mass of an atom that emits alpha particle?
An alpha particle is a positively charged nuclear particle consisting of two protons bound to two neutrons. The atomic number of an atom decreases by 2 and the mass number decreases by approximately 4 when an alpha particle is ejected.
The atomic number increases but the atomic mass stays the same?
The atomic number increases but the atomic mass stays the same after the emission of a beta particle by a radioactive atom.
What is the atomic mass-?
The atomic mass is the mass of a molecule, atomic particle or sub-atomic particle.
Which atomic particle has an atomic mass of one amu but no net charge?
This atomic particle is the neutron.
The neutral particle of an atom weighing approximately one atomic mass unit?
This atomic particle is the neutron.
Which atomic particle has no mass?
Photons and neutrinos dont have mass.
Is alpha particle is heavy particle?
An alpha particle is a helium-4 nucleus. It has a mass of about 4 atomic mass units.
Which particle has the least amount of mass?
The 'rest mass' of the photon is zero ... but the photon is never at rest, and it has plenty of mass at the speed of light, at which it is always traveling. so that let's the photon out. Amongst particles that actually have rest mass, but not much of it, the neutrino probably has the least.
Which subatomic particle is least massive?
The three main subatomic particles are the proton, neutron, and electron. Of these three, the electron has the least amount of mass at about 0.0005 amu or atomic mass units.
What is the atomic particle whose mass can be ignored?
Electron
Can you use the atomic number and atomic mass to calculate the number of each subatomic particle?
atomic number = number of protons = number of electrons atomic mass = mass of protons + mass of neutrons
What is a positively charger particle with a mass of 1.673x10-24g?
atomic mass unit
What happens to atomic number and atomic mass of an atom that emits alpha particle?
An alpha particle is a positively charged nuclear particle consisting of two protons bound to two neutrons. The atomic number of an atom decreases by 2 and the mass number decreases by approximately 4 when an alpha particle is ejected.
What particle is least massive?
The least massive principle atomic particle is the electron. Neutrons and protons are much more massive and are about equal in mass. Of course, there are even smaller particles such as quarks which are less massive than even electrons.
