What elements are in the 17th group?

The halogen elements are the six elements in Group 17 of the periodic table. Group 17 occupies the second column from the right in the periodic table and contains fluorine (F), chlorine (Cl), bromine (Br), iodine (I), astatine (At), and tennessine (Ts).

What are the characteristics of Group 17 elements?

What is the most active element in Group 17?

The most active element in Group 17 is FLUORINE.

What element is in Group 17 and period 3 of the periodic table?

Chlorine is a halogen in group 17 and period 3. It is very reactive and is widely used for many purposes, such as as a disinfectant. Due to its high reactivity, it is commonly found in nature bonded to many different elements.

Why are Group 17 called halogens?

The group 17 elements include fluorine(F), chlorine (Cl), bromine(Br), iodine(I) and astatine(At) from the top to the bottom. They are called “halogens” because they give salts when they react with metals.

Why is chlorine in Group 17?

Because the halogen elements have seven valence electrons, they only require one additional electron to form a full octet. This characteristic makes them more reactive than other non-metal groups.

What is the Valency of Group 17 elements?

All the Group 17 elements have the same outer electronic configuration, and that is ns2 np5, where ‘n’ stands for the shell number. As can be seen from the electronic configuration, the outermost shell of the halogen atoms have 7 electrons; thus, their valency is 7.

Why are Group 17 elements called halogens?

What is the name or symbol of the element in group 17 and period 2?

Name of group seventeen’s second period’s element is Fluorine and it’s symbol is F.

What element is located in group 17 and period 5?

The halogens are located on the left of the noble gases on the periodic table. These five toxic, non-metallic elements make up Group 17 of the periodic table and consist of: fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At)….Elements.
