The element you are describing is highly conductive, highly reactive, soft, and lustrous, which suggests it is a metal. Specifically, these properties are characteristic of alkali metals, which belong to Group 1 of the periodic table. Alkali metals, such as lithium, sodium, and potassium, are known for their high reactivity, softness, and good electrical conductivity. Therefore, the element most likely belongs to Group 1 (alkali metals).
Atomic number quick check. An element is highly conductive, highly reactive, soft, and lustrous. The element most likely belongs to which group?
