Calcium is more reactive than beryllium because of the following reasons:

1. Atomic Size: Calcium has a larger atomic size than beryllium. This means that the outermost electrons in calcium are farther from the nucleus than in beryllium. As a result, the attraction between the nucleus and the outermost electrons in calcium is weaker, making it easier for calcium to lose electrons and react.

2. Number of Valence Electrons: Calcium has two valence electrons, while beryllium only has one. The more valence electrons an atom has, the more likely it is to react with other atoms.

3. Energy Levels: Calcium's valence electrons are in a higher energy level than beryllium's. Electrons in higher energy levels are more reactive because they are less tightly bound to the nucleus.

4. Metallic Character: Calcium is more metallic in nature than beryllium. Metallic elements tend to be more reactive because they can easily lose electrons to form positive ions.

In conclusion, due to its larger atomic size, higher number of valence electrons, higher energy level of valence electrons, and more metallic character, calcium is more reactive than beryllium.
