an electron造句怎么写

A discrete particle, such as a photon or an electron.

So in this case, we don't have enough energy to eject an electron, so, an electron is not ejected.

Great. Yup, it's going to be an electron acceptor, it wants to accept electrons, it wants to accept electron density.

A positively charged electrode, as of an electrolytic cell, a storage battery, or an electron tube.

Once an atom is ionized, it remains charged until it meets an electron.

One result is that from many atoms an electron is expelled.

The model uses indistinct and overlapping "probability clouds" to approximate the position of an electron.

The chance that an electron absorbs more than one photon is negligible.

( One electron volt is defined as the kinetic energy gained by an electron when it is accelerated by a potential difference of one volt.

An X-ray tuned to the correct energy can knock an electron out of the innermost orbital.

An ionic bond is characterized by the transfer of an electron from one atom to the other.

In the photon picture, an electron literally absorbs a blast of energy as opposed to a gradual trickle.

The matrix of dots on a CRT screen( or TV set) that emit light when bombarded by an electron beam.

An electrically neutral excited state of an insulator or semiconductor, often regarded as a bound state of an electron and a hole.

The electromagnetic radiation produced by an accelerated electrically charged subatomic particle, such as an electron, as when it is deflected by another charged particle.

Majority Carrier- A carrier, either a hole or an electron that is dominant in a specific region, such as electrons in an N-Type area.

Those who make a person accident is, this is an electron only pay one of very finite in the life application.

The fox preys farthest from home

For instance, the phosphor on a CRT screen needs to be constantly reactivated by an electron beam in order to remain illuminated.

Now this is a good place to start, because we are very familiar with ionization energy, we've been talking about it it's that minimum energy required to remove an electron from an atom.

raster scan electron beam system

So, if we do this calculation for an electron, saying it moves at 10 to the 5 meters per second, then what we end up with for a wavelength is 7 times 10 to the -9 meters.

The vacuum tube is an electron tube from which all or most of the gas has been removed, permitting electrons to move with no or low interaction with any remaining gas molecules.

A memory that is written and read by an electron beam. In the writing action the beam either does, or does not, deposit electrons according to a one or zero input. In the reading action the effect of the beam on the charged or uncharged area is detected.

What's an electron microscope?

An electron-volt is the energy with which a one-volt battery can accelerate an electron.

Those ions eventually recapture an electron and return to normal.

So, it's some way of describing an electron.

It's going to be an electron acceptor, and it wants to accept electrons and wants to accept electron density.

An electrode in an electron tube that collects electrons which have finished carrying current.

lens system focuses image on a photosensitive mosaic that is scanned by an electron beam.

The influence that spin of an electron affects energy degeneracy of one-electron system is discussed from symmetry, and the general law of the influence is produced.

Relating to or designating an electric charge of the same sign as that of an electron, indicated by the symbol( - ).

That's sometimes confusing for people, because it seems like okay, is it a photon or is it an electron.

Nobody knows if it is possible to cut an electron or quark but particle physicists keep trying.

minirapid scan electron microscope

So, what we're looking at here is the force when we have two charged particles, one positive one negative -- here, the nucleus and an electron.

vector scan electron beam system

The matrix of dots on a CRT screen(or TV set) that emit light when bombarded by an electron beam. In colour displays three different types of dots, emitting the colours red, green or blue, are tightly clustered.

The membrane structure and surface features were analyzed by FT-IR and scan electron micrography.

So this means nitrogen has low electron affinity, it doesn't actually want to gain an electron.

This is denuded of an electron, it is Na plus.

One can see the orderly texture of matter through an electron microscope.

For example, the mass of an electron is really a coupling between a left handed electron and a right handed electron, which is the antiparticle of a left handed positron.

The quantized energy values of an electron enclosed in a spherical box are calculated by solving Schrodinger's wave equation.

When the researchers looked at the seedling tissues under an electron microscope, however, they could see the nanotubes had actually entered living cells.

vector scan electron beam lithography

The anode in an electron tube.

An instrument, such as an electron microscope, that uses electronic or other processes to magnify objects.

Ionization potential (ionization energy): Amount of energy required to remove an electron from an isolated atom or molecule.

If you took high school chemistry, then you undoubtedly recall the bizarre drawings of the "orbitals" that describe where in an atom or a molecule an electron is likely to be found.

Here I am actually throwing an electron onto chlorine.

To make it travel more efficiently, researchers blasted a short burst of sound at an electron trapped in an energy well.

The secondary backscattered electron current is used to modulate the intensity of an electron beam in a cathode ray tube(CRT).

What I just spent many lectures discussing is the fact that we can not know how far away an electron is from the nucleus, so we can't actually know the radius of a certain atom.
