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).
