Copper metal is not ionic. (The metallic bonding model of ions in a sea of electrons, is just a simplifification)
No, solid copper wiring does not involve an ionic bond. Copper atoms in the wire form metallic bonds where electrons are delocalized and move freely between the atoms, creating a "sea of electrons" that holds the metal together.
Copper is a metal & solid
Copper(II) chloride is not covalent, but ionic. In its solid form, it exists as a crystalline solid with strong ionic bonds between copper and chlorine ions.
An ionic compound. Ionic compounds do not conduct electricity in their solid state because the ions are locked in place and cannot move to carry a charge. However, when melted, these ions are free to move and conduct electricity.
This is kind of a trick question. Solid copper will hold together via metallic bonds, which are something like a group covalent bond. That is, the valence electrons from every Cu nucleus form a "sea of electrons" to stabilize the positive charge.

No, solid sodium chloride is not a good conductor of electric current because it is an ionic compound. In the solid state, the ions are not free to move and carry electric charge, so it does not conduct electricity well.
most of them are metal
ionic compounds are a metal and a non-metal joined together in a bond
No, an ionic compound is made when you fuse a non metal and a metal together, the metal gives a number of its electrons to the non metal which makes the metal positively charged and the non metal negatively charged. Then the two elements are drown together through electo-static attraction. Copper and tin would make just make a metal alloy:)
Nickel is a metal and typically exists in a solid metallic form, rather than as an ionic compound. While nickel can form ionic compounds in certain chemical reactions, it is not considered an ionic solid in its pure elemental form.
No, it's a metal and a solid.
