Question

diff b/w zeffective and effective nuclear charge​

Answer 1

→ The nuclear charge is the total charge in the nucleus for all the protons. It has the same value as the number of atoms.

main difference between nuclear charge and effective nuclear charge is that the value of the effective nuclear charge is always a lower value than that of the nuclear charge.

Z effective- The effective nuclear charge is the net positive charge experienced by an electron in a multi-electron atom.

Effective nuclear charge- The effective nuclear charge is the net positive charge experienced by an electron in a polyelectronic atom

POLYELECTRONIC ATOM ⚛️ - An atom containing more than one electron.

SUMMARY- OF ABOVE - Nuclear charge is the total charge of a nucleus. Zeffective nuclear charge is the net charge that an outermost shell electron experiences.
