Given that oxygen-16 and oxygen-18 both have an atomic number of 8, how many electrons, protons, and neutrons do these oxygen atoms contain?

Respuesta :

Palmetto18
atomic number=protons
So both have 8 protons

protons=electrons
So both have 8 electrons

atomic mass=protons+neutrons
So for oxygen-16, 8+neutrons=16
Oxygen-16 has 8 neutrons
So for oxygen-18, 8+neutrons=18
Oxygen-18 has 10 neutrons

Answer:

D) Both oxygen isotopes contain 8 electrons and 8 protons but each contains a different number of neutrons - 8 and 10 respectively.
