Answer:

alkali metals

Explanation:

Fluorine is highly reactive and has an almost full outer shell, therefore, it wants to quickly gain an electron to fill its putter shell. The best materials to reach with are ones that have one electron in their outer shell.

In the laboratory, an unknown element X reacts with fluorine. The following ionic compound is obtained XF. According to the valence electrons of fluorine, the element X belong to alkali metal family.

Hence, Option (B) is correct answer.

What is Valence Electrons ?

Valence electrons are negatively charged particle in the outermost shell of an atom.

What is Ionic compound ?

The chemical compounds which is made up of ions that formed charged particles when a atom or a group of atom lose or gains electron is called Ionic compound.

Fluorine has seven valence electrons in its outermost shell. Fluorine wants only one electron to complete its octet. In group one all the alkali metals have one valence electrons in the outermost shell.

Thus from the above conclusion we can say that In the laboratory, an unknown element X reacts with fluorine. The following ionic compound is obtained XF. According to the valence electrons of fluorine, the element X belong to alkali metal family.

Hence, Option (B) is correct answer.
