<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
