When reacting with an atom of fluorine, an atom of lithium will lose an electron and become a lithium ion.

Option D

Explanation:

Most of the chemical reactions or diffusion occurs by transfer of electrons among the elements combining to form a material. So depending on the type of bonding existed in any molecule, the strength of the bonding and its directionality can be measured.

Basically two or mole elements combine to form a compound and in this process, one of the element need to give some amount of electron to the other elements. And this transfer of electrons can be known from their oxidation state. As the element is giving or taking an electron from/to other element, that corresponding donating element and receiving element will be termed as ions from atoms.

So, the element which has the tendency to give electron easily will form positive ions and similarly, the element which is known for attracting electrons towards itself is termed as negative ions. So in this case, on reaction of fluorine with lithium, the lithium will lose an electron and become a lithium ion.
