electronegativity: The tendency of an atom to attract electrons to itself. halogens: Group 17 (or VII) in the periodic table consisting of fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At). They share similar chemical properties.
Furthermore, what are characteristics of the halogens?
Physical properties of halogens
- Melting point and boiling point. The halogens have low melting points and boiling points.
- State at room temperature. Room temperature is usually taken as being 25°C. At this temperature, fluorine and chlorine are gases, bromine is a liquid, and iodine and astatine are solids.
What is unique about the actinides?
actinide series, a series of radioactive metallic elements in Group 3 of the periodic table. Members of the series are often called actinides, although actinium (at. no. 89) is not always considered a member of the series.
What do halogens do?
HALOGENS: Group 7 of the periodic table of elements, including fluorine, chlorine, bromine, iodine, and astatine. The halogens are diatomic, and tend to form salts; hence their name, which comes from two Greek terms meaning "salt-forming."
