Metallic crystals are good conductors of electricity but ionic crystals are not?

metals have free electrons that can bounce from one to another hence the 'flow' of electrons. But things like table salt, or NaCl are so tightly bound together, that the electrons dont want to leave their cozy spot they are in and so wont bounce to a different spot without something drastic happening... for example a nuclear explosion.


Are ionic crystals good conductors?

No, ionic crystals are typically poor conductors of electricity because the ions are locked in a rigid lattice structure and cannot move freely to carry electric charge. However, when ionic crystals are dissolved in water or melted, their ions can move more freely and conduct electricity.


What forms crystals covalent or ionic?

Crystals can form from both covalent and ionic compounds. Covalent crystals are held together by covalent bonds, where atoms share electrons to form a stable structure. Ionic crystals are held together by ionic bonds, where oppositely charged ions attract each other to form a lattice structure.


Why don't the electrons in an ionic lattice become "delocalized" like they do in a metal lattice, and what is the reason behind this difference in behavior?

In an ionic lattice, electrons are tightly bound to specific ions and do not move freely throughout the lattice like in a metal lattice. This is because in an ionic lattice, the ions have opposite charges and form strong electrostatic attractions that hold the electrons in place. In contrast, in a metal lattice, the electrons are delocalized because the metal atoms share their outer electrons, allowing them to move freely throughout the lattice.


Will elements with electrons that are not tightly held more likely form ionic or covalent bonds?

Elements with electrons that are not tightly held are more likely to form ionic bonds because they have a tendency to lose or gain electrons to achieve a stable electron configuration. This typically occurs in elements with large differences in electronegativity, leading to the transfer of electrons and the formation of ionic compounds. Bonds between such elements are typically less likely to form covalent bonds.


Can crystals ever be made out of covalent bonds or is it strictlly only ionic?

Crystals can be made from covalent bonds as well as ionic bonds. Covalent crystals are formed when atoms share electrons, creating a network of interconnected atoms with strong directional bonds. Diamond and quartz are examples of covalent crystals, while sodium chloride (salt) is an example of an ionic crystal.


Why do solid crystals of ionic compounds conduct electricity when the crystals dissolve in water?

Solid crystals of ionic compounds do not conduct electricity because the ions are not free to move. When the crystals dissolve in water, the ionic bonds are broken and the ions become free to move, allowing them to carry electric current.


Is diamond a ionic crystal?

No, diamond is not an ionic crystal. Diamond is composed of carbon atoms covalently bonded to each other in a three-dimensional crystal lattice structure, rather than being formed by the transfer of electrons between positively and negatively charged ions as in ionic crystals.


Can crystals have what bonds between their atoms?

Yes, crystals can have both ionic and covalent bonds between their atoms. Ionic bonds involve the transfer of electrons between atoms, resulting in the attraction of positively and negatively charged ions. Covalent bonds involve atoms sharing electrons to form a stable bond between them.


Why ionic crystals don't conduct electricity in the solid state?

In the solid state ionic crystals are not dissociated in ions.


How is the position of electrons involved in metallic bonding different from the position of electrons that form ionic and covalent bonds?

the electrons involved in metallic bonding are delocalised - they are free to move which accounts for electrical conductivity. In ionic bonds the electrons are tightly bound to individual atoms. Generally covalent bonds have localised electrons, in pairs in individual bonds. However there are delocalised electrons in some situations - take graphite extensive pi bonds allow for delocalisation and electrical conductivity.


Why are metals very good conductors of electricity a Covalent bonding c Ionic bonding b They are shiny and very hard d Delocalized valence electrons?

d) Metals are very good conductors of electricity because they have delocalized valence electrons that are free to move within the metal structure. This allows for the easy flow of electric current through the material.
