Ionic compounds conduct electricity when molten (liquid) or in aqueous solution (dissolved in water), because their ions are free to move from place to place. Ionic compounds cannot conduct electricity when solid, as their ions are held in fixed positions and cannot move.
Ionic compounds conduct electricity when in molten (liquid) and aqueous (dissolved in water) state since the ions are free to move.
Diamond is a covalet crystal.
The definition of ionic bond is when a positively charged ion forms a bond with a negatively charged ions and one atom transfers electrons to another. An example of an ionic bond is the chemical compound Sodium Chloride.
hope it helps u
mark me the brainliest please
In chemistry, an ionic compound is a chemical compound composed of ions held together by electrostatic forces termed ionic bonding. The compound is neutral overall, but consists of positively charged ions called cations and negatively charged ions called anions
In the formation of cation, the radius of the cation is generally smaller than its atom. For Na, when it loses an electron, its outer shell will be removed thus having a smaller ionic radius. It will have a similar configuration to that of Neon.
The electronic configuration for Na atom is 2,8,1 (z=11) and electronic configuration for Na ion is 2,8 (z=10). There is a removal of the m shell and hence, the ion is smaller in size. After removal of one electron, the effective nuclear charge on sodium atoms increase due to which nucleus tends to attract the electrons with a greater force and thus, causing a shrink in size.
Hope this helps uh ✌
diamond is a I think metallic crystal
Ionic compounds exist in solid form. They have high melting point because the force of attraction is very strong between the ions.
It is the bond which includes electrostatic attraction between oppositly charged ions
molten state.Ionic solids are insulators in solid state but conductors in molten state and in aqueous solutions
yes its a very good app
mark it as brainiest
