Which property do metalloids share with nonmetals? both are brittle. both are shiny. both have low melting points. both are very conductive.

Both are Brittle

Explanation:

Metals are lustrous, malleable and ductile. Metals are good conductors of heat and electricity.

Non-metals are poor conductors of heat and electricity. Non-metals are brittle and non-lustrous elements.

Elements which have properties between metals and non-metals are known as metalloids.

Some mettaloids are lustrous and conductors of electricity. One property that these elements share with non-metals is that these are brittle i.e. they can easily break.

The property metalloids share with nonmetals is .

Further explanation:

Nonmetals:

Elements that gain electrons in a chemical reaction are non-metals. They are the electronegative element that has high ionization energy. Non-metals are either gas, liquid or solid. Nonmetal oxides react with bases and form salts.

Properties of Nonmetals:

Physical State: Most non-metals exist in the form of gas and solid. The exception includes bromine that exists as liquid at room temperature.

Non-Malleable and Ductile: They are brittle and cannot be transformed into wires.

Conduction: Poor conductor of heat.

Luster: Non-metals have no metallic luster.

Melting and Boiling Point: Melting point of non-metals is lower than metals. Also, it is highly variable.

Metalloid:

An element that is a mixture of metals and nonmetals is called metalloids. The six known metalloids are boron, silicon, germanium, arsenic, antimony, and tellurium.

Properties of Metalloids:

Metalloids are metallic brittle solids.

Mostmetalloids are semiconductors and thermal conductors.

Some metalloids conduct electricity like metals.

1. Metalloids are brittle and also nonmetals are very brittle. Hence, both metalloids and nonmetals have this property. Hence option 1 is correct.

2. Metalloids can be either shiny or dull but nonmetals are dull. Hence, option 2 is incorrect.

3. Metalloids have melting points as similar to metals whereas nonmetals have melting points lower than metals. Hence, option 3 is incorrect.

4. Some metalloids conduct electricity like metals whereas nonmetal does not conduct electricity. Hence, option 4 is incorrect.
