Electron charge, (symbol e), fundamental physical constant expressing the naturally occurring unit of electric charge, equal to 1.602176634 × 10−19 coulomb. In addition to the electron, all freely existing charged subatomic particles thus far discovered have an electric charge equal to this valu The elementary charge's value is approximately 1.602 x 10-19 coulombs, so this means that the charge of an electron is -1.602 x 10-19. That's the quick version of an electron's charge, but it would be beneficial to examine what an elementary charge is and how it affects the properties of electrons. Electrons And Elemental Charges
[/caption] The charge of the electron is equivalent to the magnitude of the elementary charge (e) but bearing a negative sign. Since the value of the elementary charge is roughly 1.602 x 10-19. The elementary charge, usually denoted by e or sometimes q e, is the electric charge carried by a single proton or, equivalently, the magnitude of the negative electric charge carried by a single electron, which has charge −1 e. This elementary charge is a fundamental physical constant.To avoid confusion over its sign, e is sometimes called the elementary positive charge Electric charge is the physical property of matter that causes it to experience a force when placed in an electromagnetic field.There are two types of electric charge: positive and negative (commonly carried by protons and electrons respectively). Like charges repel each other and unlike charges attract each other. An object with an absence of net charge is referred to as neutral Atoms that lose an electron become ions with a +1 charge, since there is now one more proton than electrons. Atoms that gain an electron have one more electron than protons and become a -1 ion. Chemical bonds that hold atoms together to form compounds result from these changes in the number and arrangement of electrons
The charge on an atom is related to its valence electrons or oxidation state. An atom of an element is most stable when its outer electron shell is completely filled or half-filled. The most common charges are based on maximum stability for the atom. However, other charges are possible In physics, an electronvolt (symbol eV, also written electron-volt and electron volt) is the amount of kinetic energy gained by a single electron accelerating from rest through an electric potential difference of one volt in vacuum. When used as a unit of energy, the numerical value of 1 eV in joules (symbol J) is equivalent to the numerical value of the charge of an electron in coulombs. The ratio of electric charge on an electron to the mass of that electron is called specific charge.i.e. Charge on electron(e)=1.67*10^—19 coulomb Mass of electron(m)=9.1*10^—31 kg By defination, specific charge on electron is e÷m 1.67*10^—19÷9.1*1..
