Itâs a good idea to start thinking in these terms because itâs fundamental to making an entire painting read right with depth recession. Here is the definition for hue, value and chromatic intensity. 1  HUE: In painting color theory, a hue refers to a pure color â one without white or black pigment added to it. 2  Color and hue in painting mean the same thing to most artists. 3  The primary hues are red, yellow and blue.
In chemistry and atomic physics, the main group is the group of elements whose lightest members are represented by helium, lithium, beryllium, boron, carbon, nitrogen, oxygen, fluorine, and neon as arranged in the periodic table of the elements.
In the periodic table of the elements, each numbered column is a group. In chemistry, a group (also known as a family) is a column of elements in the periodic table of the chemical elements.There are 18 numbered groups in the periodic table, but the f-block columns (between groups 2 and 3) are not numbered.n the old IUPAC system the letters A and B were designated to the left (A) and right (B) part of the table, while in the CAS system the letters A and B are designated to main group elements (A) and transition elements (B).
