Answer:
D.) H-O
Explanation:
Polarity is determined based on the difference in electronegativity of the atoms. The greater the difference, the more polar the bond. The general trend is that the atoms in the top-right corner of the periodic table are the most electronegative.
A.) is incorrect because H-H has no electronegativity difference, making it nonpolar.
B.) and C.) are incorrect because their electronegativity differences are not the greatest.
D.) is correct because the electronegativity difference between the H and O is the greatest.

Water. All organisms that depend on oxygen need water to live.
Answer:
Explanation:
How do I describe an ion?
<h2>an ion is an atom that has had electrons added or taken away from it.</h2><h2>they do this in order to obtain a stable electronic configuration like their closest noble gas..see Periodic Table column 18 which is also column VIIIA</h2><h2>If they gain electrons, they are negative and are called</h2><h2>ANIONS</h2><h2>if they lose electrons they are positive and are called</h2><h2>CATIONS </h2><h2 />
Chlorine atom has 17 electrons. It<span> has seven </span>valence electrons<span>. These seven electrons make </span>chlorine<span> a very reactive element. A </span>valence electron<span> is an </span>electron<span> that is associated with an atom, and that can participate in the formation of a chemical bond. Hope this helps.</span>
