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.

What is The formal charge on the carbon atom in the carbonate ion?
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
What are the charges for an electron and a proton?
A proton has a positive charge of +1 An electron has a negative charge of -1 An neutron has no charge
Give the electrical charge of electron?
The electrical charge of the electron is negative. Proton is positive Neutron is neutral Electron is negative
What is the charge on a electron called?
the charge of a proton is called positive charge neutron- negative charge electron- no charge
What are the relative charges of proton neutron and electron?
Proton's have a positive charge, neutron'shave a neutral charge, electron's have a negative charge
Why is the total charge of an electron neutral?
electron is negatively charged, not neutral.
Is total electric charge conserved in electron capture?
Yes. Total electric charge is always conserved. No exceptions are known.
What is the total electron charge for francium?
Francium has 87 electrons but the atom is neutral.
What is The formal charge on the carbon atom in the carbonate ion?
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
Who discovered the charge to mass ratio for the electrons?
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.
How can you find Charges of ions?
Assume that every electron= -1 and every proton=+1... add the total numbers of electrons and protons together and the sum is the charge
How in law of conservation of charge the total charge on an isolated system remains constant and give with an example?
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.
What part of the atom has a negative charge is the?
Electron Carries A Negative Charge.
Does an electron or proton have a larger 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.
Is the charge of a electron always equal to the charge on a neutron?
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.
What does a electron have?
Electron's have a negative charge, Protons have a positive charge.
The charge on an electron?
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.
