Question

An unknown element has chemical behavior similar to that of silicon (Si) and lead (Pb). The unknown element has a mass greater than that of sulfur (S), but less than that of cadmium (Cd). Use the periodic table to determine the identity of the unknown element.

Answer 1

The answer to your question is Germanium

Step-by-step explanation:

Process

Follow the clues to find the answer

1.- Behavior similar to that of Si and Pb.

Elements of the same group have similar properties so this element could be:

Carbon, Germanium or Tin

2.- Mass greater than sulfur

Sulfur has a mass of 32

So, the element we are looking for could not be Carbon

3.- Mass less than Cadmium

Cadmium has a mass of 48, so this element could no be Tin

4.- The element we are looking for is Germanium.
