18.998

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

Answer 1

Here is the information for the element Fluorine (F):

• Atomic Number: 9
• Atomic Mass: 18.998
• Number of Protons: 9
• Number of Neutrons: 10 (calculated as: Atomic mass (approximately 19) - Atomic number (9) = 10)
• Number of Electrons: 9 (in a neutral atom, the number of electrons equals the number of protons)

So, to summarize:

• Atomic Number: 9
• Atomic Mass: 18.998
• Number of Protons: 9
• Number of Neutrons: 10
• Number of Electrons: 9
