They react with metals to form compounds called salts. 2- The term 'halogen' is a Greek word which means 'salt former' because they react with metals to form compounds called salts. they exist naturally in various mineral salts in […] Reactive elements of Group 17 that are poor conductors. Group 17 elements are called “halogens” because they give salts when they react with metals. navanathmote14 navanathmote14 Answer: Indonesia I thick but true. Because the halogens are highly reactive, none is found in nature as the free element. The halogens react violently with alkali metals, which have one valence electron. The halogens are located on the left of the noble gases on the periodic table. Because they produce alkaline aqueous solutions. Group 17 Periodic Table. Group 17 elements exist as diatomic molecules (X 2) when not combined with other elements. Answer. 14. The elements of Group 17 are called halogens and following are the elements with electron configuration. 48) What is the oxygen-to-hydrogen mass ratio for H2O2? 1- The elements in this group are all non metals. 1 ; Because the element in the group are reactive nonmetal which has seven valence electrons. Group 1 elements are indeed called alkali metals because of what happens when they react with water. Most elements in Group 17 are called halogens, although the classification of element 117, tennessine (Ts), is still being studied. There is considerable confusion surrounding the Group labels. Oxygen is abundantly found on the earth. Share 0. For example, the halogen chlorine (Cl) and the alkali metal sodium (Na) react to form table salt, or sodium chloride (NaCl). Period and Group: The Periodic Table is a table we use to visually organize all 118 known chemical elements. 2 0. (a) 10 (b) 4 (c) 17 (d) 21 (c) 17. New questions in Science. (b) This is because halogens are reactive non-metals. The members of this group are highly similar to each other. New questions in Science. Noble Gases. Occurrence of group 16 elements of the modern periodic table. Chlorine is in group 17 of periodic table, also called the halogens, and is not found as the element in nature - only as a compound. Group 17 elements are called halogens because halogen is a Greek word which means 'salt producing'. Thus, in the outermost shell of these elements, the number of electrons is 7. This is a reasonable belief because the noble gases have a complete octet, making them very stable and unlikely to gain or lose any electrons. The elements of group 17 are called 2 See answers shrishtikukreri128 shrishtikukreri128 Answer: halogens is right answer . fluorine F[He]2s22p5 chlorine Cl[Ne] 3s23p5 … why are group 17 elements called halogens. 4 ; View Full Answer why is acidity decreasing from left to right ina period? Periodic Table of Element Groups . Hydrochloric acid, which is a component of aqua regia (a mixture of HCl and HNO 3 that dissolves gold), and the mineral fluorspar (CaF 2 ) were well known to alchemists, who used them in their quest for gold. Group 17 is called the halogen family, and the group to its right is called the noble gases. highly reactive elements that belong to Group 1. The most common of these being salt, or sodium chloride, and the potassium compounds sylvite (or potassium chloride) and carnallite (potassium magnesium chloride hexahydrate). 2020-2021 cbse chapter 5 class 10 class 10 science ncert periodic classification of elements science. Halogens means salt producers.The elements present of group 17 i.e Cl,Br etc react with metals to form salts and therefore called halogens. What do the elements in Group 17 have in common akajajajaj is waiting for your help. 0. (b) … Elements in group 17 are called halogens (see Figure below). What is the atomic number of element of period 3 and group 17 of the Periodic Table? Group 16 is the third last group in the periodic table.This group is called the oxygen family or the chalcogens.The elements in this group are oxygen, sulfur, selenium, tellurium, polonium and livermorium.The first three elements are nonmetals and the last two are semimetals.Polonium and livermorium are radioactive. Group 17 elements are called Halogens. mugdha736 mugdha736 The elements of group 17 are called Halogens. Transition metals. Physical and Chemical Properties of Group 17 Elements Group 17 Elements: The Halogens The elements in Group 17 are: Fluorine Chlorine Bromine Iodine Astatine These elements are known as halogens. Thanks please see my … Group 17 (7a) elements are called. Elements in group 17 are called Halogens. the number of protons in the nucleus. Physical and Chemical Properties of Group 17 Elements . None.

Physical and Chemical Properties of Group 17 Elements Group 17 Elements: The HalogensThe elements in Group 17 are: Fluorine Chlorine Bromine Iodine Astatine These elements are known as halogens. For example, flourine reacts explosively with sodium to form sodium fluoride. Group 2 elements that have two valence electrons . Alkali metals. (a) Halogen is a Greek word which means salt-former’.
