Answer:
An element that belongs to group 17 of the periodic table is a halogen, and will have physical and chemical characteristics like that of nonmetals.
Explanation:
Halogens are nonmetals, and include five elements: fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At). They are all nonmetals, and are quite toxic.
Halogens become darker as you go down the group. Fluorine is a very pale yellow, while bromine is red-brown. Halogens have relatively low melting and boiling points as well.
An element belongs to group 17 of the periodic table. This element is most likely a Halogens
A solid of this element would have a black, metallic appearance.
What are the 17th group elements?
halogen, any of the six nonmetallic elements that constitute Group 17 (Group VIIa) of the periodic table. The halogen elements are fluorine (F), chlorine (Cl), bromine (Br), iodine (I), astatine (At), and tennessine (Ts).
Characteristics of Halogens
A unique characteristic of halogens is that it is the only group in the entire periodic table that is composed of elements that belong to all three classical states of matter (solid, liquid, and gas), when kept under standard conditions of pressure and temperature.
