Which statement about metals and nonmetals is correct?

Question

A. Metals can be hammered into thin sheets, and nonmetals are brittle
B. Metals and nonmetals can both be found in any column of the periodic table
C. Metals tend to be poor conductors of electricity, while non metals are strong conductors of electricity
D. Most metals are a solid under normal conditions, and monst nonmetals are a liquid

Answer 1

The correct statement about metals and nonmetals is:

A. Metals can be hammered into thin sheets, and nonmetals are brittle.

• Metals are malleable, meaning they can be hammered or pressed into thin sheets without breaking. Nonmetals often exhibit brittleness and can shatter when force is applied.

The other statements are incorrect for the following reasons:

B. Metals and nonmetals can both be found in any column of the periodic table: This is not correct as elements in certain groups (like 1 and 2) are primarily metals, while nonmetals are found in other specific groups (like 15, 16, and 17).

C. Metals tend to be poor conductors of electricity, while nonmetals are strong conductors of electricity: This is incorrect as metals are typically good conductors of electricity, whereas nonmetals are usually poor conductors (with exceptions like graphite).

D. Most metals are a solid under normal conditions, and most nonmetals are a liquid: This is also false; most nonmetals are gases or solids at room temperature, with bromine being the only nonmetal that is a liquid.
