Respuesta :
Lithium is to be considered as an ION
Atom is defined as its natural state where it will have all its electrons present in its shell
Since in this case Lithium is giving its electron so after giving the electron it will become an ion
Compound is the combination of two or more different atoms
Molecules is the combination of same type of atoms
So here answer must be
C) ion
Answer: C) ion.
Explanation:
An atom is the smallest entity of any matter which may or may not have independent existence.
Compound is a pure substance which is made from atoms of different elements combined together in a fixed ratio by mass.
Ion is formed by a neutral atom or loss or gain of electron. Loss of electron results into positively charged ion called as cation and gain of electron results in negatively charged ion called as anion.
Lithium is an atom with atomic number 3 and thus lose 1 electron to attain stable configuration.

Molecule can be formed by combination of similar elements or combination of different elements.
