When comparing all the given elements, the one that reacts similarly to the element lithium (Li) is sodium, so the best choice is D.
When comparing the properties of the given options with the properties of lithium, the one that has similar chemical characteristics as Li is Na because they are in the same group of the periodic table.
Elements are located in the periodic table in groups (columns) and periods (rows). The elements located in the same group, have similar chemical properties because they have the same number of outermost electrons located in the same outermost orbital.
In the case of Na, it is located in the same group as Li (alkali metals) in the s-block of the periodic table, so it has one outermost electron located in the s-orbital (3s¹), which is the same as Li (2s¹). This group is characterized for being soft metals and because they can react explosively with water.
The other given options have different properties:
Therefore, the best choice is option D: Sodium (Na).
