In another universe the electrons are described by four quantum numbers p, q, r, and s. the rules for these quantum numbers are as follows. • p = 1, 2, 3, 4, 5, ; • q takes on positive odd integers and q ≤ p; • r takes on all even integer values from −q to +q; • s = ±1/2. (a) sketch what the first four periods of the periodic table will look like in this universe. (b) what are the atomic numbers of the first four elements you would expect to be least reactive? (c) give an example, using elements in the first four rows, of ionic compounds with the formulas, of ionic compounds with the formulas xy, xy2, x2y, xy3, and x2y3. (d) how many electrons can have p = 4, q = 3? (e) how many electrons can have p = 3, q = 0, r = 0? (f) how many electrons can have p = 6?

It would be (at) + cu (s)

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
