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

Answer 1

For the element Zinc (Zn), with the atomic number 30 and atomic mass approximately 65.39, we can derive the other properties as follows:

• Atomic Number: 30 (This indicates the number of protons.)

• Atomic Mass: Approximately 65.39

• Number of Protons: 30 (same as the atomic number)

• Number of Electrons: 30 (in a neutral atom, the number of electrons equals the number of protons)

• Number of Neutrons: To calculate the number of neutrons, we can use the formula:

  \[ \text{Number of Neutrons} = \text{Atomic Mass} - \text{Number of Protons} \]

  The atomic mass of Zinc (rounded to the nearest whole number) is approximately 65. Therefore:

  \[ \text{Number of Neutrons} = 65 - 30 = 35 \]

So, summarizing:

• Atomic Number: 30
• Atomic Mass: 65.39
• Number of Protons: 30
• Number of Neutrons: 35
• Number of Electrons: 30
