what is shielding effect ?how it affects atomic size in lanthanides
Answers
Answer:
The Lanthanide Contraction is the result of a poor shielding effect of the 4f electrons. The shielding effectis described as the phenomenon by which the inner-shell electrons shieldthe outer-shell electrons so they are not effected by nuclear charge.19-
Answer:
Electrons in an atom can shield each other from the pull of the nucleus. This effect, called the shielding effect, describes the decrease in attraction between an electron and the nucleus in any atom with more than one electron shell.
