Answer:
b is the answer
Explanation:
non metals are not shiny, brittle, unmalleable, and are poor conductors of thermal energy and electrical current.
A nonmetal is brittle, dull, and low in density.
• Non-metals refer to the elements that produce negative ions by gaining or accepting electrons. The non-metals generally possess 4, 5, 6, or 7 electrons in their valence shell. The non-metals are those, which are devoid of all the metallic properties.
• The non-metals in their solids-state are brittle, thus, they lack ductility and malleability exhibited by the metals.
• The non-metals are not shiny like metals, they are dull in color.
• The non-metals seem to possess low density, primarily as non-metals seem to prevail either in a liquid or solid-state. The non-metals lack the dense and closed packing in the lattice, which is seen in metals.
Thus, non-metals are brittle, dull, and low in density.
