Answer:
Atomic number Z = 8
as atomic number is equal to number of protons So, there are 8 protons in the oxygen 16 and oxygen 18
And number of protons is equal to number of electrons so there are 8 electrons in both oxygen 16 and oxygen-18.
Number of neutrons = Mass number - Atomic number
so, number of neutrons in oxygen-18 = 18 - 8 = 10
and number of neutrons in oxygen-16 = 16 - 8 = 8
