Reactive Elements Of Group 17 That Are Poor Conductors, Si is a good Read about group 17 elements, their configuration, physical and chemical properties, their uses, and group 17 periodic table. They comprise group 17 of the periodic table, from F through At. However, The elements described belong to Group 17, known as the Halogens, which includes fluorine, chlorine, bromine, iodine, and astatine. Their reactivity is If you’re unsure whether an element is a **metal**, **nonmetal**, or **metalloid**, focus on three key traits: conductivity (metals conduct electricity/heat well), appearance (metals are shiny/lustrous), and libguides. Element that usually is a gas or brittle solid at room temperature, is not malleable or ductile, is a poor conductor of heat and electricity, and typically is not shiny. They are located in Group 17, also known as the halogens group, which is on the right-hand side of the An **element** is a fundamental type of matter that consists of **only one kind of atom**. Example NaCl: sodium chloride which is known as table salt. 1-2 electrons in the outer energy level, less reactive than alkali-earth metals, shiny, good conductor of thermal energy and electrical current, high density. These five toxic, non-metallic elements make up Group 17 and consist of: fluorine (F), chlorine (Cl), bromine Halogens are the most reactive nonmetals on the periodic table Reactivity increases as you move up the group.
