| Atomic symbol | Atomic Number | Protons | Neutrons | Electrons | Atomic mass |

Question

|---------------|---------------|---------|----------|-----------|-------------|
| Mo | __ | __ | 53 | __ | __ |

Answer 1

To fill in the table for Molybdenum (Mo), we will use its atomic number, which is 42. For Molybdenum, the atomic mass is typically around 95.94 u (atomic mass units).

Here’s the completed table:

| Atomic symbol | Atomic Number | Protons | Neutrons | Electrons | Atomic mass | |---------------|---------------|---------|----------|-----------|-------------| | Mo | 42 | 42 | 53 | 42 | 95.94 u |

Notes:

• The atomic mass listed is an average based on isotopic abundance, and it may vary slightly depending on the source.
• The number of electrons is equal to the number of protons in a neutral atom.
