How can i find nuclear charge and overall charge while only knowing the atomic mumber, number of protons and electrons?​
Mazyrski [523]

Explanation:

An atom is made up of:

  • Protons which are the positively charged particles
  • Electrons are negatively charged
  • Neutrons carry no charges.

Atomic number is the number of protons in an atom.

To find the nuclear charge:

    We use the effective nuclear charge formula:

   Effective nuclear charge = Atomic number - number of shielding electrons(non-valence electrons)

The shielding electrons are the non-valence electrons in the inner orbitals.

For example:

  Ne:

          atomic number = 10

          Effective nuclear charge = 10 - (2) = 8+

   Number of non-valence electrons is 2

The effective nuclear charge is 8+

Overall charge:

        Charge = number of protons - number of electrons

  For neutral atoms, the overall charge is zero as the number of protons and electrons are the same.
