The lightest halogen is, which means that A is the right answer to this question. Are you familiar with Fluorine? If you are not, you do not have to worry because this is not one of the well-known elements. This is one of the lightest halogens though so you are bound to remember it now that you have learned this detail.

This is the most electronegative element in the periodic table too. This means that it can be very reactive. It will react with almost all aspects. Based on the experiments that were done with the use of this element, the only items that it does not respond with are neon and helium.

A is the answer to this question. There are a lot of people who have heard about the halogen Fluorine but they do not know what this is. This element is known to be highly toxic. You will know what this is based on its appearance which is usually pale yellow. This is an electronegative element which also means that it can be very reactive.

It has been tested to react with the different elements and in almost all cases, there were reactions that took place. The only elements that it will not react are neon and helium. Some similarities of fluorine to fluoride have made people concerned about the safety and use of fluoride. This can only become dangerous in very large quantities.
