which of the following statements are true about nonmetals? select all that apply a they can exist as solids, liquids, or gases b they have a wide variety of properties, most of which are the opposite of metals. c they make up the majority of the periodic table of elements. d they tend to have higher melting points than metals.

which of the following statements are true about nonmetals? select all that apply a they can exist as solids, liquids, or gases b they have a wide variety of properties, most of which are the opposite of metals. c they make up the majority of the periodic table of elements. d they tend to have higher melting points than metals.

Answer

Brief Explanations:

Non - metals can exist in all three states of matter (solids like carbon, liquids like bromine, gases like oxygen), so a is true. Non - metals have properties opposite to metals such as being poor conductors of heat and electricity (while metals are good conductors), so b is true. Metals make up the majority of elements in the periodic table, not non - metals, so c is false. Non - metals generally have lower melting points compared to metals, so d is false.

Answer:

A. They can exist as solids, liquids, or gases B. They have a wide variety of properties, most of which are the opposite of metals.
