To determine the element found in the pectates of the middle lamella, let's analyze the options provided:

1. **Understanding Pectates**: Pectates are salts of pectic acid, which is a component of plant cell walls, primarily in the middle lamella. The middle lamella acts as a glue between plant cells, providing structural integrity.

2. **Element Associations**:
- (a) **Magnesium**: Primarily involved in chlorophyll and enzyme activities, not mainly associated with pectates.
- (b) **Iron**: Essential for certain metabolic processes, particularly in chlorophyll formation, but not for pectates.
- (c) **Molybdenum**: More related to nitrogen fixation and enzyme function, less significant in the middle lamella.
- (d) **Calcium**: Known to play a critical role in stabilizing the middle lamella by interacting with pectins, providing firmness to plant tissues.

3. **Conclusion**: Given that calcium is a key element in the structure of pectates in the middle lamella, the correct answer is:

### Final Answer
(d) calcium
