electrons造句

What do these electrons represent?

Three unpaired electrons in nitrogen.

In covalent bonding, atoms share electrons.

Oxidation involves the transfer of electrons.

All the electrons fall into the nucleus.

Now, how about this repulsion between electrons?

How do we put electrons into such a system?

Under normal conditions, atoms contain two electrons per energy level surrounding their protons, with the electrons spinning in opposite directions.

We need to fill in a total of four electrons.

The electrons would not be moving around at random.

Both holes and electrons can move around within them.

The electrons go on to form a useful direct current.

Electrolytes produce electrons and while under charge, the electrons move between the plates discharging energy in the form of volts.

Yeah, so also 4. We started with 10 valence electrons, we used up 6 of those as bonding electrons, so we have 4 left, which will be lone pair electrons.

So a plus two ion means that we're removing two electrons from the atom and the electrons that we're going to remove are always going to be the highest energy electrons.

Because step five is that we need to fill in our bonding electrons, and we start it with filling in two electrons per bond.

In this scenario, all the electrons eventually scatter during their long trip along the sandwich: the spin-up electrons from one iron layer and the spin-down electrons from the other.

As electrons moved through the nanotube, they became excited and released excess energy, which then created even more electrons flowing through the tube.

Negatively charged objects try to give up their excess electrons to neutral bodies, while positively charged materials try to extract electrons from neutral bodies.

"The thermal wave squeezes electrons out of the nanotubes like a tube of toothpaste," Strano explained.

When photons with sufficient energy strike the silicon they create pairs of electrons and holes.

However there are notable differences between light waves and those associated with electrons.

Particles that require antisymmetric wave functions, such as electrons, are called fermions.

Remember, every time we have two electrons that are being Shared, that's a single bond.

At the junction where the two layers meet, electrons pair up with holes, establishing an electric field that prevents electrons from moving from the n-type material to the p-type.

A nonpolar covalent bond happens when both atoms have the same strength of electric attraction for the Shared electrons.

The way that we can figure this out is using something called bond order , and bond order is equal to 1/2 times the number of bonding electrons, minus the number of anti-bonding electrons.

Prof Kubiatowicz's findings are based on the fact that, while downloading an e-book does not change the number of electrons in an e-reader, those electrons holding data have a higher level of energy.

From the beginning when I had this idea, it seemed to me that there would be symmetry between the holes and the electrons and therefore the holes must have the same mass as the electrons.

Only electrons in the outer shell can form chemical bonds, so the elements in each column are chemically similar.

Using relativistic theory to calculate high energy electrons, there is an inability to overcome the speed limitation crisis.

The density of holes in the base is less than the density of free electrons in the emitter and collector .

When an atom loses one or more electrons it acquires a positive charge and is known as a cation.

A plasma containing 1018 electrons per cubic centimeter (an unexceptional number) can generate a wave with a peak electric field of 100 billion volts per meter.

Considering the disturbance of the plasma electrons at the beam-ion channel boundary, the eigen-equation of TM mode has been derived.

The results show that backward electron emission yield deviates from inverse cosine law, due to the role of the valence electrons of H2 +.

Hla says it should be possible to grow the wires on semiconductors or insulators as well and prove that electrons superconduct along the wires.

When you stride across a wool carpet in leather shoes, your shoes pick up extra electrons from the carpet with each step.

Under the laws of quantum mechanics, the nuclei of atoms have shell-like structures analogous to the spheres in which given Numbers of electrons exist in certain orbits around the nucleus.

So you'll notice in your problem-set, sometimes you're asked for a number of orbitals with a set of quantum Numbers, sometimes you're asked for a number of electrons for a set of quantum Numbers.

The sensors rely on quantum tunnelling, in which electrons take journeys that would not be allowed by the laws of classical physics, as long as the distances involved are tiny.

As proved by the experiments, a number of free electrons and holes are existed in the unexposed silver halide emulsion micro-crystals. These factors are all essential to the fog center formation.

An external circuit provides a path for the electrons to return to the p-type material, producing an electric current along the way that continues as long as light strikes the solar cell.

所以大家看碱金属及碱土金属：,一个电子，lithium，，one，electron，两个，，and，then，beryllium，，magnesium，，two，electrons，所有的方法都是,让他们达到Ne，Ar的稳定结构。

"Although benzene is often represented with alternating single and double bonds between carbon atoms, the electrons in the bonds are shared or delocalized in such a way as to make all carbon-carbon bonds alike. Benzene is a colourless, mobile liquid with a characteristic odour."
