Question

question 2 5 pts how many protons, neutron and electrons in an oxygen atom with anatomic mass of 16? would need more information 16 protons, 8 electrons, 8 neutrons 8 protons, 8 electrons, 8 neutrons answer is not possible.

Explanation:

Step1: Recall atomic number of oxygen

Oxygen has an atomic number of 8. Atomic number = number of protons = number of electrons in a neutral atom. So, number of protons = 8 and number of electrons = 8.

Step2: Calculate number of neutrons

Atomic mass = number of protons + number of neutrons. Given atomic mass = 16 and number of protons = 8. Then number of neutrons = 16 - 8 = 8.

Answer:

C. 8 protons, 8 electrons, 8 neutrons
