Advertisements The space surrounding the nucleus is occupied by the electrons, moving so rapidly that we can think of them as being everywhere at once. (Note: This is not very accurate, but it will suffice for now.)An electron is not part of the atomic nucleus, but orbits the nucleus. It carries a unit-negative electric charge (i.e. -1.60 x 10-19 C). An electron is nearly mass-less. It has a rest mass of 9.11 x 10-31 kg. The rest mass of a proton is 1836 times the rest mass of an electron.
In a neutral atom, the number of electrons is the same as the number of protons. Circulating electrons are held in orbit by the influence of protons' positive charge.
Do you know?
The electron has an anti-matter counterpart called the positron. This anti-particle has precisely the same mass, but it carries a positive charge. If it meets an electron, both are annihilated in a burst of energy.
The hydrogen nucleus is unique in having no neutron, only a single proton.

Unnatural Acts: affect bias
This misperception may be due in part to the strong negative emotive content that the word carries, compared to the emotive meaning of less-charged words like and The affect bias is at work in ... read moreTechLab: Science 6 - Study Guide
1. Electricity begins at the level where protons and electrons have electric charge. 2. carry a positive charge. 3. Electrons carry a charge. 4. form when atoms lose or gain electrons and become ... read moreEssay on Solar Energy
They do their job silently and there are no moving parts to wear out. It is no wonder that one marvels on how such a device would function. To understand how a solar cell works, it is necessary to go back to some basic atomic concepts. In the simplest model of the atom, electrons orbit a central nucleus, composed of protons and neutrons. each electron carries one negative charge and each proton one positive charge. Neutrons carry no charge. Every atom has the ... read moreOn gravity « pgtruspaces blog
In solid state electronics an area is doped to have "holes," positive, low charge areas next to "filled,"negative, high charge areas so a small charge change can cause charge units to fall into the holes and start current flow. A visual representation is a pile ... The creation of neutrons is the key to this part of the proposition. A free neutron under standard ....
