Periodic Table/electronic configuration/ bonding MYP3 Assessment ISÄ Teacher: Vivi Apostolou Periodic Table/electronic configuration/ bonding 1. MYP3 The diagram below shows part of the periodic table of elements. The shaded area contains only metal elements. Two other areas also contain only metal elements. Which areas contain only metal elements? Tick the two correct boxes. A B 2. C D E The diagram below shows the periodic table of elements. C A D E B (a) ISÄ F Which elements have similar physical and chemical properties and do not conduct electricity? __________________________ Teacher: Vivi Apostolou Periodic Table/electronic configuration/ bonding (b) MYP3 Which elementsโ electrons have occupied the same number of electron shells around the atom? (two pairs) __________________________ (c) 3. Which elements belong to the family of noble gases.____ (a) The periodic table is organized into ___ horizontal ________ which are called ________and ___ vertical _____which are called _______.Elements in the same______ have similar physical and chemical properties. (b) Elements can be metal or non-metals. Complete the table: Metals Properties: (i) Non-metals Properties: (i) (ii) (ii) (iii) (iii) (iv) Write the name and symbol of 5 metals: ISÄ Write the name and symbol of 5 nonmetals: Teacher: Vivi Apostolou Periodic Table/electronic configuration/ bonding MYP3 4. True or False Gold is a good conductor of heat One of the best conductors of electricity is copper. Sonorous is a characteristic of metals. We use non-metals to make bells because they ring when they are hit. The only liquid metal at room temperature (250C) is Bromine. Carbon is a non-metal and is solid at room temperature. Non-metals are not shiny. They are dull. All the metals are solids at room temperature Steel is an element. There are magnetic metals: iron, cobalt and nickel. Alloy is a mixture of metals. Steel is an alloy which contains mostly iron. 5. Metals are malleable; Give an example of such a metal that we use in our kitchen. 6. Oxygen and chlorine are gases at room temperature. Are they metals or non- metals? What kind of bonding could they form with other elements? Explain your answer. 7. Write two elements that belong to the 17th family. Are these elements metals or non-metals? ISÄ Teacher: Vivi Apostolou Periodic Table/electronic configuration/ bonding MYP3 8. Write two elements that belong to the 1rst family. Are these elements metals or non-metals? 9. If we take a piece of silver and a piece of carbon (the graphite form) which one is going to break easily if we press them and why? 10. The electronic configurations of four elements are given. Which element is found on the left-hand side of the Periodic Table? Explain. a. 2 b. 2, 8, 7 c. 2, 8, 8 d. 2, 8, 8, 2 11. Element X has a nucleon number of 40. The electron arrangement of a neutral atom of X is 2,8,8. Which of the following statements about element X are correct? It has 40 neutrons in its nucleus. It has 2 electrons in its outer shell. It is unreactive. It is in Group VIIIA of the Periodic Table. 1 and 2 b. 1 and 3 c. 2 and 4 d. 3 and 4. 1) 2) 3) 4) a. 12. a. b. c. d.

The table shows information about four different compounds. Which compound contains ionic bonds? Explain. Draw the outer electronic shell of the atoms and explain your answer. 14. a. b. c. d. The symbol for an atom of neon is 20 10๐๐ . Which statement about the atom is correct? Explain. It contains half as many neutrons as protons. It contains twice as many neutrons as protons. The number of neutrons equals the number of protons. The total number of neutrons and protons is thirty. 15. (a) The electronic configurations of two particles X and Y are: X:2,8,8,2 and Y:2,8,8 Each of these particles has 20 protons in their nucleus. (i) State and explain which one of these particles, X or Y, is an ion. (ii)Write the electronic configuration of 17๐ถ๐ and 8๐.
