There are several ways to tell metals and nonmetals apart. Nonmetalsdon't have a metallic appearance. Unlike metals, they typically have lower melting and boiling points and tend not to conduct heat or electricity very well.

B) usually gain electrons easily, poor conductors of heat, poor conductors of electricity
Nonmetals are a group of elements found on the right side of the periodic table. They have distinct properties that differentiate them from metals. The properties associated with nonmetals are:
1. Gain Electrons Easily:
Nonmetals have a tendency to gain electrons to achieve a stable electron configuration. This is because nonmetals have a higher electronegativity, which means they have a stronger attraction towards electrons. As a result, they are more likely to form negative ions (anions) by gaining electrons.
2. Poor Conductors of Heat:
Nonmetals are generally poor conductors of heat. This is because their atomic structure does not allow for efficient transfer of thermal energy. Nonmetals lack the free-flowing electrons that enable metals to conduct heat effectively. Instead, nonmetals have tightly bound electrons and limited mobility, inhibiting the transfer of heat energy.
3. Poor Conductors of Electricity:
Similar to heat conduction, nonmetals are also poor conductors of electricity. Unlike metals, which have a delocalized sea of electrons that allow for the flow of electric current, nonmetals have tightly bound electrons and limited electron mobility. Therefore, nonmetals do not readily conduct electricity.
Examples of nonmetals include elements like oxygen, nitrogen, carbon, sulfur, and chlorine. These elements exhibit the properties mentioned above.
In contrast, the other options listed in the question do not accurately describe the properties of nonmetals:
a) Nonmetals do not usually donate electrons easily. Instead, they typically gain electrons.
c) Nonmetals do not typically conduct heat and electricity well. They are poor conductors in both cases.
d) Nonmetals do not have metallic luster, and they are generally poor conductors of heat.
Therefore, the correct answer is option 'b,' which accurately describes the properties of nonmetals.
