electric charge

The state of any particle or body on which the there is an imbalance between electrons and protons. An excess of electrons causes a negative charge; a deficiency of electrons causes a positive charge. Electric charge, ELECTRIC FORCE and ELECTRIC POTENTIAL DIFFERENCE are fundamental to much of physiology.

On the side with two hydrogen atoms, the protons aren't balanced out as well by electrons, so that side has a bit of positive charge.
It follows that any excess of CE[C.sub.T] over AEC, or vice versa, at p[H.sub.0] must be due to net permanent negative or net permanent positive charge, respectively, i.e.
As a result of variation in the magnitude of the soil solution pH or ionic strength, the equilibrium relationship between the adsorbed N[O.sub.3] and the positive charge density is likely to be altered.
This causes the chitosan to lose its positive charge, and the strands begin to come back together.
There is a great deal of variety in how a cloud can become electrified, and the graphic shows an instance in which electrical breakdown traveled from a region of negative charge toward and through a lower region of positive charge. We chose it because it represented real data for a flash that the New Mexico Tech scientists found intriguing.--Alexandra Witze
Although the mechanism discussed by Donn and Menzies (2005) may apply to the formation of the N[O.sub.3] accumulations, N[O.sub.3] adsorption and accumulation should occur throughout the whole profile since a positive charge of 1-2.5 [cmol.sub.c]/kg is exhibited at most depths in the profiles containing N[O.sub.3] accumulations (Donn et al.
The amount of positive charge on the nucleus was called the atomic number.
Polyamines are molecules within the cell that carry a positive charge.
The new method, known as TrEnDi (trimethylation enhancement using diazomethane), increases the sensitivity of mass spectrometry analyses by assigning a fixed, permanent positive charge to amino groups.
Exposure to ultraviolet rays in sunlight drives out electrons and gives the dust a positive charge. But at night-time or in shadow, the torrent of particles spewed out from the Sun charges the dust with electrons, giving it a negative charge.
In the process, though, they shorted out much of the positive charge that usually sits near the top of the cloud acting like a lid on a pot to keep negatively charged leaders from breaking through.
The other terminal has a deficit of electrons and, therefore, a positive charge. When wires connect the two terminals to form a circuit, electrons flow through the wires to try to even out this difference in charge.
