What are the properties of a photon?
A photon is a fundamental particle of light that has no mass, travels at the speed of light, and carries energy and momentum. It behaves both as a particle and a wave, and can be absorbed or emitted by atoms.
What units do scientists use in order to measure mass of atoms in their subatomic particles?
Scientists use atomic mass units (amu) or unified atomic mass units (u) to measure the mass of atoms and their subatomic particles. These units are based on the mass of a carbon-12 atom and are commonly used in the field of nuclear and particle physics.
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 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.
What escape velocity of a particle of mass m varies as?
The escape velocity of a particle of mass m is independent of the mass of the particle. It is solely dependent on the mass and radius of the object it is trying to escape from. The escape velocity is given by the formula: (v = \sqrt{\frac{2GM}{r}}), where G is the gravitational constant, M is the mass of the object, and r is the distance from the center of the object to the particle.
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 particle has the smallest mass atoms or electron?
An electron has a much smaller mass than any atom.
What two particle's account for almost all of the mass of an atom?
Protons and neutrons.
Which has the smallest mass?
Hydrogen has the smallest atomic mass at roughly 1.008 grams per mol (6.02x10^23 atoms)
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.
Particle with a large mass and a posiive charge?
A particle that has a large mass and a positive charge is known as an alpha particle. These particles contain 2 protons and 2 neutrons which are bound together to form an identical particle to a helium nucleus.
Which particles account for most of the atoms mass?
Physics has not managed to discover a particle that accounts for mass
What tells you how heavy an element's atoms are compared with atoms of other elements?
The atomic mass of an element tells you how heavy its atoms are compared with atoms of other elements. Atomic mass is the average mass of an atom of an element, taking into account all its isotopes and their abundance.
What are the properties of a photon?
A photon is a fundamental particle of light that has no mass, travels at the speed of light, and carries energy and momentum. It behaves both as a particle and a wave, and can be absorbed or emitted by atoms.
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
