Problem: Classify these atoms and ions as paramagnetic or diamagnetic.ZnFe3+ZrAl3+

FREE Expert Solution

We’re being asked to classify each ion as diamagnetic or paramagnetic.

Recall that for:

• diamagnetic: all of the electrons are paired

• paramagnetic: at least one electron is unpaired

For neutral element, Atomic Number = # of protons = # of electrons.

For Zn:

Step 1: Electron configuration

Atomic # = 30 → 30 e-

 Nearest noble gas before Zn   Ar (18 e)

The shorthand e config. for Cu is:

Zn: [Ar]4s23d10

Step 2: Orbital diagram

Outermost sublevel: 3d 5 orbitals (d)

When filling up the orbitals, take note of:

• Aufbau Principle: totally fill in the lowest energy orbital first

• Hund’s Rule: electron orbitals that are degenerate (same energy orbital) are first half-filled before they are totally filled
