body-centered cubic
coordination number in bcc is 8 coordination number in simple cubic is 6
Coordination Numbers/Geometry Ca CN=8 Cubic coordination F CN=4 Tetrahedral coordination
Oxygen is a non metallic element. Mass number of it is 16.
According to Wikipedia: "In diamond each carbon atom is at the centre of a tetrahedron formed by four other carbon atoms, so the coordination number is four..."
Calcium fluoride has the fluorite structure where each calxium ion has 8 fluoride ions as near neighbours at the corners of a cube, and eacf fluoride has 4 calcium ions ate the corners of a tetrahedron. Another way of looking at this is that the calcium ions are close packed and the fluroide atoms fill the "tetrahedral holes" In calcium chloride the chloride ion is too large to allow eight coordination and the coordination around the calcium drops to 6, the coordination around the chloride has to drop to 3. This gives CaCl2 a unique structure which is a distorted form of the more regular rutile structure adopted by TiO2.

Oxygen has a proton number of 8, meaning that it has 8 electrons. The electronic structure of oxygen is 2.6 This means that the number of electrons in the second shell is 6.
Spice Up My Kitchen - 2007 Metallic Mishmash 1-8 was released on: USA: 26 June 2007
There are (8) factory paint colors; Midnight Blue Metallic, Gold Mist Metallic, Summit White, White Diamond Tricoat, Carbon Black Metallic, Red Jewel Tintcoat, Quicksilver Metallic, and Mocha Steel Metallic. White Diamond Tricoat, Carbon Black Metallic, and Red Jewel Tintcoat are all available at an additional cost.
Electronic structure is how many electrons each shell of an atom can hold. It is written by the number of electrons in the 1st shell (max 2) then a commer, the number of electrons in the 2nd shell (max 8) another commer, how many are in the 3rd shell (max 8) etc. example: 2,8,8
