Same number of valence electrons cause same properties. The elements with same properties are grouped together. For example- the alkali metals are placed in group-1
An octahedron is a closed 3-d shape with 8 polygonal faces. There are 257 topologically different convex octahedra. The properties of octahedra will depend on which of these 257 shapes you have in mind. Furthermore, the properties of any of these octahedra can be modified if the shape is altered by stretching of skewing (twisting) the shape.
What are the propertiesof Hardwoods? Hardwoods are deciduous and loose their leaves in winter. They are harder than softwoods except Balsa wood. They are a Broadleaved trees which belong to the 'Angiospermae' or flowering plant such as fruits or seeds. They are usually found in more temperate zones. They are generally more durable than softwoods and have a wider range of colour than softwoods. They are more expensive than softwoods and are used for veneers on products, for furniture, for flooring and utensils.

The speed of light through anything is determined by the electrical propertiesof that environment, specifically the electrostatic permittivity and the magneticpermeability. The result of what those numbers happen to be in empty spaceis 299,792,458 meters per second.Is there some reason that you'd expect that speed to be difficult for light ? I knowit seems to be impossibly fast when you think about it or measure it. But snails andants feel the same way when they watch you walking around. It's all relative.
