If number of electrons in an atom is 8 and number of protons is also 8, what is the atomic
number of the atom?
Correct Answer:
D. 8
Explanation:
The atomic number of an atom is defined by the total number of protons located within its nucleus. In a neutral atom, the number of protons and electrons is identical to maintain electrical balance. Since the atom in question contains 8 protons, its atomic number is 8. This specific atomic number identifies the element as oxygen.
