Explanation:
Because it is the smallest sub-atomic particle
I think it is called a loess. Please correct me if I am wrong.
<u>Answer:</u> The ion formed by lithium element is 
<u>Explanation:</u>
Ions are formed when an atom looses or gains electrons.
If an atom gains electrons, it leads to the formation of negative ions known as anions. For Example: Fluorine gains 1 electron to form
ions.
If an atom looses electrons, it leads to the formation of positive ions known as cations. For Example: Sodium looses 1 electron to form
ions.
Lithium is the 3rd element of the periodic table having 3 electrons.
The electronic configuration of lithium element = 
This element will loose 1 electron to attain stable electronic configuration and will lead to the formation of
ion.
Hence, the ion formed by lithium element is
