Yes.
yes
yes
Yes
Not in their standard solid states, but they can if molten or dissolved in water.
All do - some just have greater conductivity than others
yes all materials conduct electicity , but some are good conductor , some poor and some very poor
Not in its usual solid state. But like other ionic compounds calcium chloride will conduct electricity if molten or dissolved in water.
Yes, barium chloride is a strong electrolyte. When dissolved in water, it dissociates completely into its ions, barium and chloride ions, allowing it to conduct electricity effectively.
The thermal conductivity of Barium is expressed by the formula :18.4 W·m−1·K−1, So, yes, the chemical element, Barium conducts heat. However, compounds of Barium may have different degrees of thermal conductivity.
No, argon is a non-metal noble gas that does not conduct electricity because it has a full outer electron shell and lacks free electrons for carrying electric charge.
Yes, barium nitrate is a strong electrolyte. When dissolved in water, it dissociates into ions, allowing it to conduct electricity effectively.
Barium itself is not a good conductor of electricity; it is a metal that generally exhibits low conductivity compared to more conductive metals like copper or aluminum. However, when barium is in the form of barium salts or compounds, such as barium chloride, it can conduct electricity in solution due to the presence of ions. The conductivity of these solutions depends on the concentration of the barium ions and other ions present.
