A sample of matter was given the following description: The sample of the pure substance is blue in color with an octahedral sha
Alexeev081 [22]

Answer:

A crystalline solid

Explanation:

Most solids form with a regular arrangement of their particles because the overall attractive interactions between particles are maximized, and the total intermolecular energy is minimized, when the particles pack in the most efficient manner. The regular arrangement at an atomic level is often reflected at a macroscopic level.  Liquids dont use to have this kind of arrangements or shapes.

if the spin of one electron in an orbital is clockwise , what is the spin of the other electron in that orbital
nata0808 [166]

Here we have to get the spin of the other electron present in a orbital which already have an electron which has clockwise spin.

The electron will have anti-clockwise notation.

We know from the Pauli exclusion principle, no two electrons in an atom can have all the four quantum numbers i.e. principal quantum number (n), azimuthal quantum number (l), magnetic quantum number (m) and spin quantum number (s) same. The importance of the principle also restrict the possible number of electrons may be present in a particular orbital.

Let assume for an 1s orbital the possible values of four quantum numbers are n = 1, l = 0, m = 0 and s = \frac{+}{-}\frac{1}{2}.

The exclusion principle at once tells us that there may be only two unique sets of these quantum numbers:

1, 0, 0, +\frac{1}{2} and 1, 0, 0, -\frac{1}{2}.

Thus if one electron in an orbital has clockwise spin the other electron will must be have anti-clockwise spin.
