Transcribed Image Text:**Magnetic Behavior of Substances**
Understanding how a substance behaves in a magnetic field provides essential insights into the arrangement of its electrons. Molecules with one or more unpaired electrons are attracted to a magnetic field, and the strength of this attraction increases with the number of unpaired electrons. Conversely, substances with no unpaired electrons are weakly repelled from a magnetic field.
**Molecular Orbital Arrangement**
### Diagram Explanation
The diagram (Figure 1) illustrates the molecular orbital energy levels for diatomic molecules or ions. The orbitals shown from top to bottom are:
- \( \sigma^*_{2p} \)
- \( \pi^*_{2p} \)
- \( \sigma_{2p} \)
- \( \pi_{2p} \)
- \( \sigma^*_{2s} \)
- \( \sigma_{2s} \)
Each orbital has empty boxes that represent places where electrons can be filled.
### Activity Instructions
**Objective:** Classify each of the 16 diatomic species based on their magnetic properties into either diamagnetic or paramagnetic categories.
- **Diamagnetic** substances have all electrons paired and are slightly repelled by a magnetic field.
- **Paramagnetic** substances have one or more unpaired electrons and are attracted to a magnetic field.
**Steps:**
1. You have 16 diatomic species, each with a different number of valence electrons.
2. Species 1 starts with one valence electron, species 2 has two, and so on.
3. Drag each species into the appropriate bin: Diamagnetic or Paramagnetic.
**Hints Available**
To assist with classification, view available hints to guide your decisions based on the electron configuration and the resultant magnetic behavior of each species.
**Interactive Features:**
- **Reset** the activity to start over.
- Access **Help** for additional guidance.

Transcribed Image Text:### Understanding Magnetic Properties of Molecules
**Magnetic Behavior of Substances:**
The way a substance behaves in a magnetic field provides crucial insights into the arrangement of its electrons. Molecules with one or more unpaired electrons are attracted into a magnetic field, known as paramagnetic. The more unpaired electrons present, the stronger the attraction. In contrast, substances with no unpaired electrons are weakly repelled by a magnetic field, which is referred to as diamagnetic.

**Activity - Classifying Magnetic Properties:**
**Part B:**
You have 16 diatomic molecules or ions with a given valence molecular orbital arrangement (as shown in Figure 2). These species vary in their numbers of valence electrons:
- Species 1 has one valence electron,
- Species 2 has two valence electrons, etc.
**Task:**
Classify the species as diamagnetic or paramagnetic by dragging the appropriate items (species) into their respective bins labeled ‘Diamagnetic’ and ‘Paramagnetic’.
---
**Molecular Orbital Diagram (Figure 2 Explanation):**
The molecular orbital arrangement follows this sequence from bottom to top:
- \( \sigma_{2s} \)
- \( \sigma^*_{2s} \)
- \( \sigma_{2p} \)
- \( \pi_{2p} \)
- \( \pi^*_{2p} \)
- \( \sigma^*_{2p} \)
Each orbital level has boxes for placing electrons. The presence of unpaired electrons in any of these orbitals will determine whether the molecule is paramagnetic.
Use these insights to determine which category—diamagnetic or paramagnetic—each species belongs to based on their electron configuration.
