12

Question

Mg
Magnesium
24.305

Atomic number
atomic mass
# of protons
# of neutrons
# of electrons

Answer 1

For Magnesium (Mg), here's the breakdown of the requested information:

• Atomic Number: 12
• Atomic Mass: Approximately 24.305
• Number of Protons: 12 (The atomic number indicates the number of protons)
• Number of Neutrons: The number of neutrons can be calculated by subtracting the atomic number from the atomic mass (rounded to the nearest whole number).
  • Neutrons = Atomic Mass - Atomic Number
  • Neutrons = 24 - 12 = 12 (for the most common isotope)
• Number of Electrons: In a neutral atom, the number of electrons equals the number of protons, so there are also 12 electrons.

Here's a summary:

• Atomic Number: 12
• Atomic Mass: 24.305
• Number of Protons: 12
• Number of Neutrons: 12 (common isotope)
• Number of Electrons: 12
