Similar Elements to Sodium (Na)

Name two elements that have the same properties as sodium (Na).

Which two elements have similar properties to sodium? What group do they belong to on the periodic table?

Answer:

Two elements that have the same properties as sodium (Na) are potassium (K) and lithium (Li).

Sodium is classified as an alkali metal and belongs to Group 1 of the periodic table. Elements in Group 1 share similar characteristics due to their valence electron configuration. Potassium and lithium also belong to Group 1, making them chemically similar to sodium.

Both potassium and lithium exhibit properties common to alkali metals, such as being soft, highly reactive, and readily losing their outermost electron to form a positive ion. This similarity is due to their shared valence electron configuration, which influences their chemical behavior.

Being situated in the same group on the periodic table, potassium and lithium possess comparable chemical properties to sodium. Their atomic structures and reactivity mirror that of sodium, making them elements with similar properties within the alkali metal family.
