how charge is measured
Charge can be measured and is called electric dipole moment, , in units called debye (D). (SI: C.m)

Re: how charge is measured
We can calculate the charge by using the formula: FC: V - ( L + B)
FC - Formal Charge
V - Valence Electrons
L - Total number of lone Pairs
B- Total number of bonds
FC - Formal Charge
V - Valence Electrons
L - Total number of lone Pairs
B- Total number of bonds

Re: how charge is measured
You can measure the formal charge of an element by using the equation
FC = V - (L - 1/2B)
FC means the formal charge
V is the amount of valence electrons (possible for each element)
L is the total amount of lone pairs
B total number of bonds (with other elements)
FC = V - (L - 1/2B)
FC means the formal charge
V is the amount of valence electrons (possible for each element)
L is the total amount of lone pairs
B total number of bonds (with other elements)

Re: how charge is measured
Charge is determined by whether or not the atom posses more or less electrons in the lewis structure bonding than what its supposed to have in its valence shell according to the periodic table. If it has extra electrons, it will take on a negative charge, and fewer electrons will result in a positive charge.

Re: how charge is measured
You should use this formula: FC = V - (L - 1/2B) to calculate the charge of each atom, and then add/substract them together to find the overall charge of the molecule.
