Question

What elements touch the staircase in the periodic table and have properties of both metals and non-metals?

Answer 1

These elements are called metalloids.

Explanation:

A metalloid is an element whose properties are "in between" those of metals and nonmetals.

For example, metals are excellent electothermal conductors, and nonmetals are non-conductors. Metalloids are described as semiconductors. These semiconductors play some major roles in chemical engineering and programming.
