Question

| Name of Element | Element Symbol | Mass Number | Atomic Number | Protons | Neutrons | Electrons |
|------------------|----------------|-------------|---------------|---------|----------|-----------|
| Carbon | C | 12 | __ | __ | __ | __ |

Answer 1

To fill in the missing information for Carbon (C):

- **Atomic Number**: The atomic number of Carbon is 6. This is the number of protons in the nucleus of a Carbon atom.
- **Protons**: Since the atomic number is 6, the number of protons is also 6.
- **Electrons**: In a neutral atom, the number of electrons equals the number of protons, so Carbon has 6 electrons.
- **Neutrons**: The mass number is the sum of protons and neutrons. For Carbon with a mass number of 12 and 6 protons, the number of neutrons can be calculated as follows:

Neutrons = Mass Number - Protons = 12 - 6 = 6.

Now, filling in the table:

| Name of Element | Element Symbol | Mass Number | Atomic Number | Protons | Neutrons | Electrons |
|------------------|----------------|-------------|---------------|---------|----------|-----------|
| Carbon | C | 12 | 6 | 6 | 6 | 6 |
