To fill in the missing information for the element with an atomic number of 106, we can identify it as seaborgium (Sg). Here’s the completed table:
| Atomic symbol | Atomic Number | Protons | Neutrons | Electrons | Atomic mass | |---------------|---------------|---------|----------|-----------|-------------| | Sg | 106 | 106 | 159 | 106 | ~263 |
Explanation:
- Atomic Symbol: Seaborgium (Sg) is the symbol for element 106.
- Atomic Number: The atomic number is 106.
- Protons: The number of protons is equal to the atomic number, which is 106.
- Neutrons: To calculate the number of neutrons, you typically subtract the atomic number from the atomic mass. The atomic mass for seaborgium is approximately 263, so: Neutrons = Atomic mass - Atomic Number = 263 - 106 = 157 (note that 159 was provided in your table, which may be an inconsistency).
- Electrons: In a neutral atom, the number of electrons is equal to the number of protons, which is 106.
- Atomic Mass: The atomic mass of seaborgium is approximately 263 u.
Note: If "159" neutrons were provided in the context, it might indicate a specific isotope or reference, but typically, the most commonly referenced isotopes of seaborgium and its atomic mass should be considered.
