Why are metallic crystals malleable and ductile? a. the electrons are free floating, allowing them to move with the atoms when the metal is struck and the crystal lattice shifts. b. the free floating electrons conduct energy easily, and disperse the energy of being hit by a hammer or other tool, allowing them to be molded and not break. c. the crystal lattice is made of very strong ionic bonds that take a lot of energy to break. d. the atoms are arranged with alternating positive and negative charges. when struck, the lattice shifts putting positives against positives and negatives against negatives.

For cyclohexane compounds drawn in a chair conformation:   -axial bonds are vertical  -equatorial bonds are parallel to two bonds within the ring.  thus, as i assume the chair conformation is drawn:   -the x group is in an axial position, as are the five other vertical bonds.  -three axial bonds are on the top face of the ring  -the other three axial bonds are on the bottom face  the position of the second substituent on each ring carbon is equatorial.  gauche groups must be on an adjacent carbon such as carbon 6 and carbon 2, and also gauche groups are rotated by 60 degrees relative to each other.  drawing the newman projections for c1–c2 and c1–c6 aids in visualizing the groups that are gauche to the y group on c1.  click this link and watch some academic videos that may you more understand the topic
