Answer:
Oxygen 17 isotope with neutral charge
Step-by-step explanation:
The atom has 8 red protons and 8 black electrons so it is neutral. Since it has 8 protons, it has atomic number of 8, which is oxygen (O).
There are 9 blue neutrons. The mass number = #protons + #neutron = 8 + 9 = 17. Therefore it is the oxygen 17 isotope.
