while developing the periodic table, dmitri mendeleev left spaces for undiscovered elements. he predicted one such element would have properties similar to those of silicon (si). over a decade later, an element was discovered matching his description: shiny, brittle, with a high melting point, and is semiconductive. based on this information, which element is likely the one mendeleev predicted? choose 1 answer: a aluminum (al) b germanium (ge) c selenium (se) d phosphorus (p)

Answer

Answer:

B. germanium (Ge)

Brief Explanations:

Germanium is a semiconductor with properties similar to silicon, such as being shiny, brittle, and having a high - melting point. Aluminum is a metal, selenium is a non - metal with different properties, and phosphorus is also a non - metal with distinct characteristics.
