As a group, halogens exhibit highly variable physical properties. Halogens range from solid (I2) to liquid (Br2) to gaseous (F2 and Cl2) at room temperature. The chemical properties are more uniform. The halogens have very high electronegativities.Fluorine has the highest electronegativity of all elements.alogens range from solid (I2) to liquid (Br2) to gaseous (F2 and Cl2) at room temperature.

A gene can exist in many different forms, calledalleles. For example, letâs say that there is one gene which determines the color of your hair. That one gene may have many forms, or alleles: black hair, brown hair, auburn hair, red hair, blond hair, etc. You inherit one allele for each gene from your mother and one from your father. Each of the two alleles you inherit for a gene each may be strong (dominant) or weak (recessive).
How much gray you have will alter your hair color values and the actual color. For example, if you have naturally warm brown or auburn hair, you could be considered platinum if 80% of your hair is gray, warm gray if 50% of your hair is gray, and auburn with white âhighlightsâ if 10% of your hair is gray.ince gray hair is a cool temperature, the more you have (length of hair and amount of gray), the more dominantly cool you will be. Cool core wardrobes consist of blacks, grays, whites and blues with the values working with your own personal color values.
