Which two layers of Earth are mainly composed of metallic elements such as nickel and iron, which are abundant in meteoroids and

Bingel [31]

This layer of the earth lies between the mantle and the solid inner core. It is the only liquid layer, a sea of mostly iron and nickel about 1,400 miles. The lava is mostly made up of iron and nickel. The outer core creates the Earth's magnetic field. The final layer is the inner core, which is 900 miles deep. Scientists believe the inner core is a solid ball of iron and other minerals.

Answer:

See the image attached. It is taken from an online chemistry textbook.

See the explanation below.

Explanation:

Sodium chloride consits of sodium cations (positive ions), Na⁺, and chloride anions (negative ions), CL⁻.

Pure sodium chloride is packed in crystals: sodium ions and chloride ions are packed together and the ions are in fixed positions. There are not free electrons that can move. Thus, sodium chloride doesn't conduct electricity, because there are no electrons or ions which are free to move.

In aqueous solution, sodium chloride units dissociates into their ions:

$NaCl\rightarrow Na^++Cl^-$

Those ions are freely to move in the solution, and such they are charge carriers, which conduct the electricity.

As explained above, in solid sodium chloride, the ions cannot move and there is not flow of current.

That is why solid pure salt of NaCl does not conduct electricity and the solutions of NaCl do conduct electricity.

The image attached show both diagrams. In the diagram A, the ions are packed together, showing that they cannot move. In the diagram B, the ions are dissolved in water, showing that they can move and carry the charge, allowing the flow of current.
