Which properties do metalloids share with metals? both are shiny and are brittle. both are very conductive and are dull. both are brittle and are gases at room temperature. both are shiny and are solid at room temperature.

Option (d) is the correct answer.

Explanation:

Metalloids are the species which show properties of both metals and non-metals. Metalloids are moderately able to conduct heat and electricity. Generally metalloids are solid at room temperature. They are also able to react with other molecules.

Metals are the substances which lose electrons to attain stability and hence they form cations.

Metals are good conductors of heat ant electricity and generally they are solid at room temperature. Metals have a shiny surface and they are also malleable and ductile.

Thus, we can conclude that a property which metalloids share with metals is that both are shiny and are solid at room temperature.

intermolecular forces are the forces between molecules or particles.

there are two kinds of van der waals forces: weak london dispersion forces and stronger dipole-dipole forces.

in molecule of water there are dipole-dipole forces between negatively charged oxygen from one molecule of water and positively charger hydrogen of another molecule of water.

hydrogen bond is an electrostatic attraction between two polar groups that occurs when a hydrogen atom (h), covalently bound to a highly electronegative atom such as flourine (f), oxygen (o) and nitrogen (n) atoms.
