Is halogens Group 7 or 17?
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).

Is fluorine Group 7 or 17?
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).
Why group 17 or VII A elements are 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.
What is Group 17 elements called?
a) Group 17 elements are called halogens. The name halogens are from Greek halo (sea salt) and gens (producing, forming) and thus means ‘sea salt former’. Group 17 consists of fluorine, chlorine, bromine, iodine which form. salts.

What does 7A mean on the periodic table?
Families: 1A – alkali metals. 2A – alkaline earth metals. 7A – halogens.
Where is group 7A on the periodic table?
Fluorine is a halogen, which is a group of non-metals located on the right side of the periodic table that includes fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At). Most halogens are electron-hungry, like fluorine. Halogens can also be referred to as group 7A, group 17, or group VIIA elements.

What are group 7A elements?
Is group 7A very reactive?
Halogens are the group 7A elements in the periodic table. They are highly reactive nonmetals and exist as diatomic molecules.
What are group VII elements called?
the halogens
The Group 7 elements are called the halogens. They are placed in the vertical column, second from the right, in the periodic table . Chlorine, bromine and iodine are the three common Group 7 elements. Group 7 elements form salts when they react with metals.
Is Group 17 on the periodic table reactive?
The halogens are a group of elements found in group 17 of the periodic table. Their name means salt-producer, and they are the most reactive non-metal elements.
How many halogens are there?
Depending on who you ask, there are either 5 or 6 halogens. Fluorine, chlorine, bromine, iodine, and astatine definitely are halogens. Element 117, tennessine, might have some properties in common with the other elements.
What are Group VII elements called?
Why are Group 18 called noble gases?
These gases are unreactive or inert because they do not gain, lose, or share electrons. Because they are found in such small amounts in the earth’s atmosphere, they are also known as noble gases.
What is the most active element in group 17 called?
Fluorine is a most reactive element in group 17 because of its small size and high electronegativity by which it accepts electrons easily and forms a bond with another element.
Are there metals in group 7A?
Answer and Explanation: The elements in group 7A are called halogens. Some of the present elements in group 7A are fluorine, chlorine, bromine, iodine, and astatine. They usually combine with metals and form a compound, which is an ionic salt.
Why is Group 7 elements the most reactive?
This is because group 7 elements react by gaining an electron. As you move down the group, the amount of electron shielding increases, meaning that the electron is less attracted to the nucleus. For this reason, fluorine is the most reactive halogen and astatine is the least reactive of the halogens.
