8-2. 39. P block elements are shiny and usually a good conductor of electricity and heat as they have a tendency to lose an electron. Let’s now look at the electronic configurationof these elements. MSJchem – New Syllabus Topic 3 – Group 17 elements Answers: 1) The term halogens mean ‘salt formers’. The interhalogen compounds are also potent oxidants and strong fluorinating agents; contact with organic materials or water can result in an explosion. Group 15 includes nitrogen, phosphorus, arsenic, antimony and bismuth. Watch the recordings here on Youtube! Ionisation enthalpy: They have very high ionization enthalpy because of small size as compared to other groups. 1. Estimate the radius of a Br ion. They are called “halogens” because they give salts when they react with metals. 37.

The elements oxygen, sulfur, selenium, tellurium and polonium comprise the 16th vertical column or VI A group elements in the currently used long type of periodic table. Atomic and ionic radii: Halogens have the smallest atomic radii in their respective periods because of maximum effective nuclear charge. Allotropy: All elements of Group 15 except nitrogen show allotropy. In this manner, in these elements, the n p subshell is step by step filled. GROUP 2 Elements 2+ GROUP 17 Elements 1– examples: the names end in "ide" beryllium Be2+ examples: magnesium Mg2+ fluoride F– calcium Ca2+ chloride Cl– POLYATOMIC CATION POLYATOMIC ANIONS ammonium NH 4 + –acetate C 2 H 3 O TRANSITION ELEMENTS carbonate 2 CO 3 – require Roman numerals hydrogen carbonate –HCO 3 Catenation: All of these are gases and chemically unreactive. !Mg2+ has a similar charge density to Li+, so the two elements show some similar chemistry (e.g., tendency to form useful organometallic compounds).
