1) For a molecular compound: it is the molecule.
2) For an ionic compound: it is the formula unit (made of ions).
3) For an element: it is the atom.
No, light is not an example of matter. It is an example of electromagnetic waves. However, it is considered that light is composed of photons (massless particles) and it is applied to it some theories of matter.
These particles are: proton, neutron, electron.
True, Matter is anything that takes up space and has mass<3 However, physicists say that some particles of matter are massless, such as photons.
Three of the most common substances are air, water and dirt. Just about anything that can have its molecules or particles vibrated will conduct sound.
I have no idea, I was actually looking for the answer. 3 dimensional
Zero.
photonsgravitonsBoth are bosons, there are no massless fermions although neutrinos were once believed to be massless.
The three lightest subatomic particles are electrons, neutrinos, and photons. Electrons and neutrinos have very small masses, while photons are massless.
A particle without mass is called a massless particle. Massless particles travel at the speed of light and do not experience gravitational forces. They have energy and momentum, but no rest mass. Examples of massless particles include photons (particles of light) and gluons (particles that mediate the strong nuclear force).
The significance of momentum for a massless particle is that it determines the particle's energy and direction of motion. Since a massless particle always travels at the speed of light, its momentum is directly proportional to its energy. Momentum is crucial for understanding how massless particles, such as photons, interact with other particles and fields in physics.
Massless particles traveling at the speed of light include photons, the particles of light. They have no rest mass and always move at the speed of light in a vacuum according to the theory of special relativity.
Subatomic particles with no mass are called neutrinos. Neutrinos are elementary particles that have extremely small, non-zero masses, but they are considered nearly massless in many calculations due to their very small mass values.
No, light does not have mass. It is made up of particles called photons, which are massless.
There are three known massless particles. Gauge bosons, gluons, and photons.
I suppose that gluons are smaller because these particles are massless.
== == The Higgs Boson is another theoretical particle thought to be responsible for the presence of mass in other particles that have mass. I believe the Higgs Boson is theorized to be itself massless. there are 3 known massless particles: the gauge boson, the photon, and the gluon ( the gluon isn't necessarily categorized as a free particle due to the fact that they are confined to hadrons) neutrinos were also, until recently, were thought to be massless. however, they were discovered to change flavor, which means that they must have mass.
No, electrons are subatomic particles with a negative charge. Light, on the other hand, consists of photons which are massless particles that carry energy and electromagnetic force.
