While dealing with multielectron atoms or ions, we must use the concept of effective nuclear charged, `Z_(eff)` which is calculated by the formula

Effective nuclear charge (Z*) can be calculated by using the formula

Effective nuclear charge (Z*) can be calculated by using the formula

Effective nuclear charge (Z_(eff)) for a nucleus of an atom is defined as

Effective nuclear charge (Z_(eff)) for a nucleus of an atom is defined as

Which of the following is generally true regarding effective nuclear charge (Z_(eff)) :

Which of the following is generally true regarding effective nuclear charge (Z_(eff)) :

The second ionization potential of Be is 17.98 eV if the electron in Be is assumed to move in a spherical orbit with a central field of effective nuclear charge (Z_(eff)) consisting of the nucleus and other electron by haw many units of charge in the nucleus shielded by other electrons? (the energy of electrons in first Bohr of H is -13.6 eV) If the extent of shielding by the if electron of Li atom is the same as you have calculated above , find the ionization potential of Li
