Learners identify elements using electron shell patterns, group and period relationships, and reactions such as sodium in water and reactions forming ionic compounds. Additional tasks compare early periodic tables by Newlands and Mendeleev, requiring evaluation of why Mendeleev’s arrangement was more accepted. The document also tests atomic structure vocabulary, boiling/melting point differences, and reactivity changes across groups.","1.  \nFigure 1 shows an outline of the modern periodic table.  \nJ, L, M, Q and R represent elements in the periodic table.  \n(a) Which element has four electrons in its outer shell?  \nTick (✔) one box.  \nJ  L  M  Q  R   \n(1)  \n(b) Which two elements in Figure 1 are in the same period?  \n  and    \n(1)  \n(c) Which element reacts with potassium to form an ionic compound?  \nTick (✔) one box.  \nJ  L  M  Q  R   \n(1)  \n(d) Which element forms ions with different charges?  \nTick (✔) one box.  \nJ  L  M  Q  R   \n(1)  \n[www.accesstuition.com](www.accesstuition.com)  \nPage 1 of 12  \n(e) Which element has three electron shells?
