Example #1 - write the name for Fe(NO3)2 Step #1 - decide if the cation is one showing variable charge. If so, a Roman numeral will be needed. In this case, iron does show variable charge. If a variable charge cation is involved, you must determine the Roman numeral involved. You do this by computing the total charge contributed by the polyatomic ion. In this case, NO3¯ has a minus one charge and there are two of them, making a total of minus 2. Therefore, the iron must be a positive two, in order to keep the total charge of the formula at zero. Step #2 - determine the name of the polyatomic ion. Nitrate is the name of NO3¯. The correct name is iron(II) nitrate. The common name would be ferrous nitrate.
(Atomic number) - (Number of electrons present) = (overall electrical charge of atom)
find the total charge present on 1gm electron
the formal charge of carbon in carbonate ion is 0solutionvalence electron-4non bonded electron-0and total no of bonding electrons=8formal charge = valence - non bonded - 1/2 total number of bonding electronselectron electron= 4-0-4= 0
A proton has a positive charge of +1 An electron has a negative charge of -1 An neutron has no charge
The electrical charge of the electron is negative. Proton is positive Neutron is neutral Electron is negative
the charge of a proton is called positive charge neutron- negative charge electron- no charge
Proton's have a positive charge, neutron'shave a neutral charge, electron's have a negative charge
electron is negatively charged, not neutral.
Yes. Total electric charge is always conserved. No exceptions are known.
Francium has 87 electrons but the atom is neutral.

Millikan found the charge of an electron by his famous oil drop experiment. J J Thomson determined the specific charge of the electron. That means the ratio of the charge of an electron to its mass. With these two values one can find the mass of electron by dividing the charge value by its specific charge.
Assume that every electron= -1 and every proton=+1... add the total numbers of electrons and protons together and the sum is the charge
According to the law of conservation of charge, the total charge in an isolated system remains constant. A simple example: when a magnesium atom loses two electrons to an oxygen atom the ions have charges of 2+ and 2- respectively. The total charge is zero before and after ionization.
Electron Carries A Negative Charge.
No. The electron and proton have the same amount of charge. Its just that the electron's charge is negative and the proton's charge is positive.
The charge on an electron is never equal to the charge on a neutron. An electron carries one negative charge and a neutron has no net charge.
Electron's have a negative charge, Protons have a positive charge.
An electron has a negative charge. Protons are positively charged, and neutrons have no charge. ************************* The charge is measured at 1.60217646 × 10-19 Coulombs.
