The Lanthanide Contraction Results Because

question 90

Multiple Choice

The lanthanide contraction results because

• A) the shielding effect of the d-electrons is less than that of the f-electrons.
• B) the shielding effect of the d-electrons is greater than that of the f-electrons.
• C) of the poor shielding effect of the f-electrons and the higher nuclear charge.
• D) the d-electrons shield the f-electrons from the nucleus.
• E) f-electrons interact more strongly with each other than d-electrons.

Definitions:

Inductive

Pertaining to inductance, the property of an electrical conductor by which a change in current through it induces an electromotive force (EMF) in both the conductor itself and in any nearby conductors by mutual inductance.

Capacitive

Related to the ability of a system or component to store charge and energy in the electric field, characteristic of capacitors or systems with capacitive elements.

Ripples

Fluctuations or variations in the output voltage of a power supply, often resulting from incomplete suppression of AC waveform within DC output.

Harmonics

In electrical systems, harmonics are frequencies that are integer multiples of the base fundamental frequency, leading to distortion in power systems.
