Answer:
A
Explanation:
Metal atoms are held together by metallic bonds. The metallic bonds are composed of a lattice of positive ions in a 'sea of electrons'.
The metal atoms are held together by strong electrostatic attraction between the positive ions and the 'sea of electrons' leading to high melting point of metals including copper.
Similarly, when a metal undergoes stress, the layers of the metal roll over each other but the lattice remains in place. Hence for metals such as Copper, layers of atoms in the lattice can slide over each other thereby making the metal malleable.
Metals oxidize by electron loss. Since Copper is metal, it can also be oxidized to form copper ions by loosing electrons.

Well in my experience with Solar Eclipses is that before it starts or before it is covering the moon is covering the sun there is like a shadow on one side of the sun and after the hours or minutes go by all around you everything is getting darker and a little colder than it was a few moments ago so what it would look like is something is in front of the sun or its like the moon got so close to the sun that it just blocked it and also some of the sun's rays surround the moon.<span />
