Question

Which of the following correctly identifies the composition of an oxygen atom?
A. 8 protons, 8 electrons, and 8 neutrons. B. 6 protons, 6 electrons, and 6 neutrons. C. 8 protons, 6 electrons, and 7 neutrons. OR D. 6 protons, 6 electrons, and 12 neutrons.

Answer 1

The atomic number of Oxygen is 8 .
Atomic number shows us the no of protons. In an atom the no. of protons are equal to the no, of electrons.
So oxygen is having 8 electrons and 8 protons.
Mass number of an element shows the no.of protons + no. of neutrons right?
Oxygen's mass number would be 16
We already know the no. of protons that is 8
so 16-8 would be the no. of neutrons.
So The answer would be A !

Answer 2

Medal me if u found that useful !

Answer 3
