The answer is D. To put it simply, all atom wished to become stable. The only way for that is to obtain an octet structure where the outermost shell would have 8 electrons, thus being full.
I’m pretty sure it’s B since ones charge the neutral while ones is positive, it’s an obvious difference as well/
Answer:
An element
Elements are substances that cannot be broken down into simpler substances either by physical or chemical method.
Explanation:
to find POH u need PH first
