| Calcium | __ | __ | __ | __ | __ | __ |

Answer 1

Here's the information for Calcium:

| Name of Element | Element Symbol | Mass Number | Atomic Number | Protons | Neutrons | Electrons |
|------------------|----------------|-------------|---------------|---------|----------|-----------|
| Calcium | Ca | 40 | 20 | 20 | 20 | 20 |

- **Element Symbol**: Ca
- **Mass Number**: The most common isotope of calcium has a mass number of 40.
- **Atomic Number**: 20 (this represents the number of protons).
- **Protons**: 20 (equal to the atomic number).
- **Neutrons**: 20 (calculated as mass number - atomic number, i.e., 40 - 20).
- **Electrons**: 20 (in a neutral atom, the number of electrons equals the number of protons).
