Explain the following :
The paramagnetic character in 3d-transition series elements increases upto Mn and then decreases.

Explanation

To explain the paramagnetic character in the 3d-transition series elements, we will analyze the electronic configurations of these elements and how the number of unpaired electrons affects their magnetic properties.

### Step-by-Step Solution:

1. **Understanding Paramagnetism**:
- Paramagnetic substances have unpaired electrons in their atomic or molecular orbitals. The presence of unpaired electrons leads to a net magnetic moment, causing the substance to be attracted to a magnetic field.

2. **3d Transition Series Elements**:
