Hydrogen reacts with an element to form a compound. Which element would have the most valence electrons and also be able to reac

pantera1 [17]

Answer:

Chlorine

Explanation:

Hello.

In this case, for the given elements, we are able to know that oxygen has 6 valence electrons, chlorine 7, nitrogen 5 and neon 8, therefore neon is not able to react as it already has 8 valence electrons. Besides, the element having the most valence electrons is chlorine and its reaction with hydrogen forms hydrogen chloride as shown below:

$H_2(g)+Cl_2(g)\rightarrow 2HCl(g)$

Therefore, the required element is chlorine.

Regards.
