élément du paysage | landscape component In visual assessment work, landscapes can be divided into four major elements. 1. Form is the perceived mass or shape of an object that appears unified, and which provides a consciousness of its distinction and relation of a whole to the component parts. 2. Line is the real or imagined path, border, boundary, or intersection of two planes, such as a silhouette, that the eye follows when perceiving abrupt differences in form, colour or texture. 3. Colour is a visual perception that enables the eye to differenciate otherwise identical objects based on the wavelengths of reflected light. 4. Texture is the visual feel of a landscape |

éléments du groupe III | element of group Group III consists of two subgroups: group IIIb and group IIIa. Group IIIa consists of scandium, yttrium, and lanthanium, which is generally considered with the lanthanoids, and actinium, which is classified with the actinoids. Group IIIb, the main group, comprises boron, aluminium, gallium, indium, and thallium |

éléments du groupe IV | element of group Group IV consists of two subgroups: group IVb, main group, and group IVa. Group IVa consists of titanium, zirconium, and hafnium which are generally classified as transition metals. The main group consists of carbonium, silicium, germanium, tin, and lead. The main valency of the elements is IV, and the members of the group show a variation from nonmetallic to metallic behaviour in moving down the group. The reactivity of the elements increases down the group from carbon to lead. All react with oxygen on heating |
