1 answer

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 |
