The atomic number is 16 and the atomic mass is 8.
The atomic number is 8 and the atomic mass is 8.
The atomic number is 8 and the atomic mass is 16.
The atomic number is 16 and the atomic mass is 4.
The atomic number is 4 and the atomic mass is 16.

Answer 1

the atomic number is 8 and the atomic mass is 16
The atomic number of the element is 8. This is because the atomic number is based on the number of protons or electrons. The atomic mass of the element is 16. This is because the atomic mass is equal to number of protons+the number of neutrons. Hope this helps.
