Cambridge International Advanced Subsidiary and Advanced Level in Chemistry (9701) ... 11 The Periodic Table of Elements 17 . Rubidium will react violently with cold water. The list is not exhaustive. reacts vigorously with metals to form ionic salts, halogens become less reactive down the group. 12. d (Mg and Ca are in the same group in the Periodic Table), 15. d (Group I metals donate 1 outermost electrons to form X, 18. c (Chlorine, being more reactive than At, displaces At from its aqueous salt). MissHanson AQA GCSE Christmas Science Quiz It is time to practise some questions regarding the above-mentioned topics. 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. Let us test your understanding. Periodic Table secondary school. Periodic Table of Elements. Atomic structure; 13.

Fluorine exists in diatomic molecules. Elements in Group IV can lose or gain electrons depending on reacting element. Which element reacts most vigorously with cold water? Sodium in Group I forms NaCl, so other elements in Group I does the same. London WC1R 4HQ. (in simple terms, it refers to how much an element loves an electron), Electronegativity is the tendency for an atom to attract electrons to itself, Electropositivity is the tendency for an atom to lose an electron, - Have the same atomic number (number of protons) but different mass number or different number of neutrons, low densities and melting points - these increases down the group, reacts easily in air so they're kept in oil, loses one outermost electron to form an ion of +1 charge eg. Relative atomic masses for Cu and Cl have not been rounded to the nearest whole number. So used for making water-pipes, Colourless solution turned brown. c. Fluorine is less reactive than chlorine. Free pure Physics, Chemistry, Geography and Social Studies revision notes. Note: Periodic Table is provided in paper 1, use the table if necessary when answering questions. 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. From example, we know elements in same group form same formula. How do we define a period and a group in a periodic table? d. In Group VII, the melting point of the elements increases with proton number. b.
