What is the atomic number of element of period 3 and group 17 of the Periodic Table? ; Group 17 elements can combine with nearly all the elements in the periodic table. The elements in group 17 of the periodic table are all called halogens. 2- The term 'halogen' is a Greek word which means 'salt former' because they react with metals to form compounds called salts. Get the answers you need, now! The majority of the elements … The most active element in group 17 is fluorine 13. Although astatine is radioactive and only has short-lived isotopes, it behaves similar to iodine and is often included in the halogen group.

There is considerable confusion surrounding the Group labels. So, now you know what halogens are! Question: 47) Group 17 (7A) Elements Are Also Called: A) Noble Gases. Write a short note on biosphere write a short note on biosphere those students who wants oswaal sample paper ,educart sample paper ,Notes,in pdf format then message me I will send you pdf in free of cost c. number of possible isotopes. Group 18 are called the noble gases . 15. None. The elements of group 16 are called (a) Chalcogens (b) Halogens (c) Pnicogens (d) Noble gases (a) Chalcogens. 2 See answers aladeemmanuel562 aladeemmanuel562 Explanation: The elements in-group 7 are often referred as “halogens”. The halogens are located on the left of the noble gases on the periodic table. Notes. Elements in a group have the same number of energy levels and the same valence electrons. New questions in Science. 1- The elements in this group are all non metals. C) Alkaline Earth Metals. Group 17 elements are also known as: (a) halogens (2) (name still in common use) (b) Group VIIA (name no longer used) Group 17 elements are non-metals; Group 17 elements exist as diatomic molecules (X 2) when not combined with other elements. For example, flourine reacts explosively with sodium to form sodium fluoride. They are called “halogens” because they give salts when they react with metals. 14. 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 in group VIIA (sometimes referred to as group 17) are all called _____. halogens 12. The halogen elements are fluorine (F), chlorine (Cl), bromine (Br), iodine (I), astatine (At), and tennessine (Ts). Group 17: halogens; Group 18: noble gases; In addition, groups may be idenitifed by the first element in each group - so the Group 16 set of elements is sometimes called the oxygen group. 2Na(s) + F2(g) -----> 2NaF(s) Ratio of Sulfur Dioxide learn more about the properties of halogens in this article ( c ) 17 ( VIIA!
