What is the charge of an atom?

An atom consists of a positively charged nucleus, surrounded by one or more negatively charged particles called electrons. The positive charges equal the negative charges, so the atom has no overall charge; it is electrically neutral.

How do you figure out a charge?

If you know the potential difference (V) in volts applied in a circuit and the work (W) in joules done over the period which it is applied, the charge in coulombs, Q = W / V.

How do you determine the charge of an atom or ion?

To find the ionic charge of an element you’ll need to consult your Periodic Table. On the Periodic Table metals (found on the left of the table) will be positive. Non-metals (found on the right) will be negative.

How do you find the electrons?

To calculate the numbers of subatomic particles in an atom, use its atomic number and mass number: number of protons = atomic number. number of electrons = atomic number.

What is the charge on an ion?

Since the electric charge on a proton is equal in magnitude to the charge on an electron, the net electric charge on an ion is equal to the number of protons in the ion minus the number of electrons.

What is the charge of Group 13?

The elements in group 13 and group 15 form a cation with a -3 charge each. And elements in group 14 have a charge of -4. Elements in group 16 have a charge of -2, while all the elements of group 17 are halogens with a charge of -1 each.
