Verified step by step guidance1
Identify the position of lithium in the periodic table. Lithium is in Group 1 (alkali metals) and Period 2.
Recall that elements in the same group (vertical column) of the periodic table share similar chemical properties because they have the same number of valence electrons.
Look at the options and determine which elements are in the same group as lithium. Sodium and potassium are in Group 1, while beryllium and magnesium are in Group 2 (alkaline earth metals).
Since sodium and potassium are in the same group as lithium, they share more chemical properties with lithium than beryllium or magnesium do.
Between sodium and potassium, sodium is directly below lithium in the periodic table, so it shares the most chemical properties with lithium.
