This quiz is a demo quiz created to test O level Chemistry knowledge of the student by www.donason.com d. It displaces iodine from aqueous potassium iodide. reacts vigorously with metals to form ionic salts, halogens become less reactive down the group. a. because the outermost shell of the element is full. d. Group I elements are very good conductors of electricity. given list of Group 7 elements, predict the properties of astatine. To avoid this, the metals are stored under oil, They also react vigorously with water, forming the alkaline hydroxide and releasing hydrogen gas, Because alkali metals are such reactive metals, they combine directly with reactive non-metals such as the halogens to form salts, low melting and boiling points - increases down the group, elements become darker and solidify down the group, because of their atomic size, which increases down the group, therefore it becomes more difficult for the nucleus to attract an electron to form an ion, most reactive is fluorine; least reactive is iodine, all halogens form ions with single negative charge eg F, Any halogen above another in the group will displace it from a solution of its salt ---->, least reactive elements in the gaseous state; do not form bonds, have stable electronic configuration with full electrons on their shells. Doc Brown's GCSE/, GCSE & O Level Chemistry Revision Notes. Free pure Physics, Chemistry, Geography and Social Studies revision notes. In the oxidation process, oxidation number of chlorine increased from 0 in Cl, In the reduction process, oxidation number of chlorine decreased from 0 in Cl. GROUP 1 ALKALI METALS sodium, potassium etc. 12 Sodium is in Group I of the Periodic Table. Each substance can be used once, more than once, or not at all. c. In Group I, reactivity decreases with increasing proton number. The notes available here are great for revision and studying on the go. This question is concerned with the following list of substances. 12. Elements in same group has the same number of valence shell electrons which the amount is the same as the group number. Displacement reactions are carried out to investigate the trend of reactivity of the halogens. d. Silver fluoride will be sensitive to light. The elements in the periodic table are divided into periods and groups. This website and its content is subject to our Terms and 5a. b. I hope that you find this website useful!

In fact, most elements in the Periodic Table exist as isotopes and thus their relative atomic mass is … The Periodic Table used by GCE O-Level Pure Chemistry students in Singapore Notice that chlorine (atomic number 17) has a relative atomic mass, Ar of 35.5 which is not a whole number. Eg. The group number of an element shows how many electrons there are in that particular element’s outermost shell (valence electrons). A periodic table is a listing of elements that are regulated in order of increasing atomic (proton) number. Since transition elements speed up chemical processes in industries, they saves time in manufacture, Less energy is needed for manufacture in industries, hence lower cost.
