Formal Charge on Atom Solution

STEP 0: Pre-Calculation Summary

Formula Used

Formal Charge = No. of Valence Shell Electrons-(No. of Bonding Pair Electrons/2)-No. of Non-Bonding Pair Electrons
FC = n_vs-(n_bp/2)-n_nb
This formula uses 4 Variables

Variables Used

Formal Charge - The Formal Charge is the charge assigned to an atom in a molecule, assuming that electrons in all chemical bonds are shared equally between atoms, regardless of relative electronegativity.
No. of Valence Shell Electrons - The No. of Valence Shell Electrons of an atom are outer shell electron that is associated with an atom, and that can participate in the formation of a chemical bond.
No. of Bonding Pair Electrons - The No. of Bonding Pair Electrons is the number of electrons shared in a bond.
No. of Non-Bonding Pair Electrons - The No. of Non-Bonding Pair Electrons in the valence shell are the ones not taking part in the bond formation.

STEP 1: Convert Input(s) to Base Unit

No. of Valence Shell Electrons: 7 --> No Conversion Required
No. of Bonding Pair Electrons: 4 --> No Conversion Required
No. of Non-Bonding Pair Electrons: 2 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

FC = n_vs-(n_bp/2)-n_nb --> 7-(4/2)-2

Evaluating ... ...

FC = 3

STEP 3: Convert Result to Output's Unit

3 --> No Conversion Required

Is formal charge the same as charge or partial charge?

A formal charge has a value of either a positive integer, a negative integer, or zero. A partial charge usually has a positive or negative non-integer. Each atom in a molecule has both, able to calculate the formal charge. A formal charge indicates gain or loss of electron(s) while forming covalent bond(s). A partial charge indicates which atom in a bond have a higher electronegativity and which have a lower electronegativity.

How to Calculate Formal Charge on Atom?

Formal Charge on Atom calculator uses Formal Charge = No. of Valence Shell Electrons-(No. of Bonding Pair Electrons/2)-No. of Non-Bonding Pair Electrons to calculate the Formal Charge, The Formal Charge on atom is the charge assigned to an atom in a molecule, assuming that electrons in all chemical bonds are shared equally between atoms, regardless of relative electronegativity. Formal Charge is denoted by FC symbol.

How to calculate Formal Charge on Atom using this online calculator? To use this online calculator for Formal Charge on Atom, enter No. of Valence Shell Electrons (n_vs), No. of Bonding Pair Electrons (n_bp) & No. of Non-Bonding Pair Electrons (n_nb) and hit the calculate button. Here is how the Formal Charge on Atom calculation can be explained with given input values -> 3 = 7-(4/2)-2.

FAQ

What is Formal Charge on Atom?

The Formal Charge on atom is the charge assigned to an atom in a molecule, assuming that electrons in all chemical bonds are shared equally between atoms, regardless of relative electronegativity and is represented as FC = n_vs-(n_bp/2)-n_nb or Formal Charge = No. of Valence Shell Electrons-(No. of Bonding Pair Electrons/2)-No. of Non-Bonding Pair Electrons. The No. of Valence Shell Electrons of an atom are outer shell electron that is associated with an atom, and that can participate in the formation of a chemical bond, The No. of Bonding Pair Electrons is the number of electrons shared in a bond & The No. of Non-Bonding Pair Electrons in the valence shell are the ones not taking part in the bond formation.

How to calculate Formal Charge on Atom?
