Answer:
Electrons Can Donate - 0
Electrons Can Receive- 2
Valence - 2
Explanation:
The electronic configuration of oxygen is 
. Thus in the p-orbital there is deficiency of two electrons. Hence, it can receive/share electron but it cannot donate electrons. This makes oxygen as a good electron acceptor. Since there is a deficiency of two electrons in the outermost shell of oxygen, the valence of oxygen in thus -2
<h2>The answer is </h2>
False
<h2>Explanation:</h2>
According to Sigmund Freud human consciousness have been divided into three levels of awareness: the conscious, precociousness, and unconscious. These stages are never understood by any person at the same time. There is always a transition period between these segments.
