<span>Chlorine has 7 valence electrons, but in the diagram, there are 2 chlorine atom making there a total of 14 valence electrons. There are 2 valence electrons in between the two atoms. There are 6 valence electrons around the outside of each individual chlorine atom. The electrons are arranged in groups of two around the outside of each atom.</span>

<span>-NH2 or, in its ionized form, -NH3+. Amino groups are the functional groups that bestow the "amino" in amino acid. They also readily ionize, gaining a proton (hydrogen ion), and thus serve as weak bases.</span>
Answer:
C. chromium is a metal that is less reactive than sodium.
Explanation:
Hello.
In this case, since chromium is in period 4 group VIB we infer it is a transition metal which slightly reacts with acids and poorly reacts with oxygen and other oxidizing substances. Thus, in comparison with both sodium and potassium which are highly reactive even with water as they get on fire, we can say that it is less reactive than both potassium and sodium, therefore, answer is: C. chromium is a metal that is less reactive than sodium.
Best regards.
