Question

A neutral atom has 8 electrons and 8 neutrons. Which of the following correctly represents the atom? A) carbon-16 B) oxygen-16 C) oxygen-24 D) oxygen-8 E) sultry-8

Answer 1

Answer:

D

Explanation:

Oxygen is the 8th element in the periodic table. This means that oxygen has 8 protons and 8 electrons. In order to get the number of neutrons you take the atomic weight in this case 15.9999~16 and you subtract it by the number of protons (16-8).

Answer 2

D - oxygen
It is the 8th element in the periodic table. 8 electrons, 8 neutrons when it is in its neutral state
