What are the atomic number and mass number if the number of electron in an element oxygen is 8 and the number of neutrons is 9?

The atomic number of an element is the number of protons in its nucleus, which is also equal to the number of electrons in a neutral atom. Given that the number of electrons in oxygen is 8, the atomic number is 8. The mass number is the sum of protons and neutrons in the nucleus, so for oxygen with 8 protons and 9 neutrons, the mass number is 8 + 9 = 17.
