<span>The correct answer is either Chrome (Chromium), or Aluminum. Unlike steel, these two don't rust easily and can be polished to be quite shiny, especially Chromium, which is why you'll always hear people who like cars talking about chrome wheels and chrome spoilers and things like that. They are not that good for bumpy or roads that are full of holes because they can bend much easier than steel so it can be expensive to maintain.</span>

Decide which element probably forms a compound with chlorine that has a chemical formula most and least similar to the chemical

stepladder [879]

The compound formed by chlorine and barium is $BaCl_2$ as the number of valence electrons in barium is 2 and in chlorine is 1. In this compound, barium acts as a cation and chlorine acts as an anion. The formation of the compound is as shown in the image.

Since, barium is an element of Group-2 (alkaline earth metal) so the other element that has a chemical formula most and least similar to the chemical formula of the compound formed by chlorine and barium should be from Group-2 (alkaline earth metal) only which has properties somewhat like barium. So, the element is strontium.

Strontium forms a compound with formula $SrCl_2$ in which strontium acts as a cation and chlorine acts as an anion. The formation of the compound is as shown in the image.
