Similar Properties to Sodium (Na)

Part 1:

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

Final answer:

Potassium (K) and rubidium (Rb) have similar properties as sodium (Na).

Sodium (Na) belongs to group 1 of the periodic table known as the alkali metals. Elements in the same group often exhibit similar chemical properties. Therefore, two elements that have similar properties as sodium are potassium (K) and rubidium (Rb).

Both potassium and rubidium share characteristics with sodium due to their alkali metal properties. They all have one electron in their outermost shell, making them highly reactive. They are all soft metals that can be easily cut with a knife and have low melting points.

When exposed to water, all three elements react vigorously to form hydroxides and release hydrogen gas. They also have similar atomic structures, which contribute to their alike properties.
