HYBRID Chemistry 1021 Test-1 Outline: Classification of Matter, Atomic Structure, and Isotopes Test-1 is based on “Classification of Matter, Atomic Structure and Isotopes” and will cover ALL content during week 1 to week 3 (inclusive). The test will be taken in-person during Class 1 of Week 4 and includes both online and written components. It will be 60 minutes in duration from the class start time. The test is to be completed in two parts: o Part 1 – multiple choice questions, on your computers, from Brightspace using Lockdown Browser. (Please be sure to bring your appropriate device to class, and have it ready to use for Part 1 of the test). o Part 2 – short answer questions on paper completed in class. The test is out of 30 marks. A student will not be allowed to start the test if they are 20 minutes late from the class start time, and must complete an online-based make-up test (only one allowed). If a student is late, they will not be given extra time to complete the test The tests will have a variety of questions such as short-answer, multiple choice, true/false, fill in the blanks, matching etc. The test will have a single attempt only You will be provided with the black and white version of the periodic table which will be unlabelled (no group numbers, period numbers, name of groups will be provided). Below is the outline for the Test-1. Participating in the lectures, reviewing all the lesson handouts, completing the learning checks, individual and group assignments and reviewing all additional learning resources found on the course Brightspace page will help prepare you for the test. Test 1 Key Content Focus: Matter, Periodic table, Atoms, Atomic Structure, Elements, Isotopes Matter o Classify examples of matter as element, compound or mixture Example: Which of the following describes the tap water we drink? A) element B) heterogeneous mixture C) homogeneous mixture D) compound o Differentiate between a pure substance and a mixture Example: Which of the following is a compound? A) Al B) saline (NaCl and water) C) sugar D) alloy E) (Hg and Ag) o Differentiate between a homogeneous and heterogeneous mixture Example: All the following are homogeneous mixtures except? A) tea B) coffee C) juice with pulps D) Trimix scuba diving gas (helium, nitrogen and oxygen) o Provide real life examples of pure substances and mixtures o Describe the characteristics of three states of matter (solids, liquids, gases) Example: Which of the following characteristics explain why hydrogen is a gas? A) Hydrogen does not move at all, has a definite volume and shape B) Hydrogen moves slow, has a definite volume but takes the shape of the container C) Hydrogen moves very fast and takes the volume and shape of the container D) Hydrogen moves very fast and has a definite volume (etext book pages 62-66) Periodic Table o Given the name of the element, write its correct symbol and given the symbol, write its name (Remember to learn the first 20 elements AND the additional elements discussed in class) o Use the periodic table to identify the group and the period of an element o Recognize the important properties of elements in the subdivisions of the periodic table: periods, groups, metals and non-metals Example: An element in group 2 and period 2 is?: A) Calcium B) Hydrogen C) Beryllium D) Lithium o Identify an element as metal, nonmetal or metalloid Example: an element with 2 valence electrons is a/an A) metal B) nonmetal C) metalloid D) isotope o Identify the four group classes: Alkali Metals, Alkaline Earth Metals, Halogens and Nobel Gases Example Identify the halogen in the following list?: A) Hydrogen B) Chlorine C) Argon D) Oxygen o Compare the characteristics of metals and non- metals Example: An element that can be drawn into wires and conducts electricity is best described as: A) metal B) nonmetal C) metalloid D) isotope o Provide examples and functions of elements that exist in human body Example: Which of the folloing is an alkaline earth element needed for strong bones? A) Na B) Mg C) Li D) Ca (etext book pages 100-106) Atoms and Elements  o Describe the structure of an atom o Describe the charge, mass and location in an atom for an electron, a proton and a neutron o Given the atomic number and mass number of an atom, state the number of protons, neutrons and electrons Example: If mass number of carbon is 12, it means that: A) the weighted average mass of the carbon isotopes is 12 B) the carbon atom contains 12 electrons C) the carbon atom contains 12 protons D) the carbon atom contains 12 particles in the nucleus o Recognize the Bohr structure of an atom The following Bohr atomic structure represents which element?: A) Boron B) Nitrogen C) Silicon D) Oxygen o Determine the number of valence electrons in an atom Example: An alkali metal in period 3 has a valence of: A) 1 electron B) 2 electrons C) 3 electrons D) 4 electrons (etext book pages 107-119) Isotopes o Determine the number of protons, neutrons and electrons in one or more isotopes of an element, identify the most abundant isotope of an element o Characterize and represent an element and its isotopes based on the atomic number and mass number Example: Which of the following correctly describes the number of protons, electrons and neutrons in H-1? A) 1 proton, 1 electron and 1 neutron B) 1 proton, 1 electron and 0 neutron C) 1 proton, 0 electron and 0 neutron D) 1 proton, 1 electron and 2 neutrons Example: A sample of an unknown element C has two naturally occurring isotopes. The isotope C-39 makes up 93.2% of the sample, and the isotope C-41 makes up 6.8% of the sample. Which of the following statements is true? A) The atomic mass of C will be less than 39 B) The atomic mass of C will be 41 C) The atomic mass of C will be 39.1 D) The atomic mass of C will be 40 o Represent isotopes in the following format using the number of protons, electrons and neutrons: Mass number c Atomic number Where, c is the symbol of an element Example: Draw the nuclear symbol for the following: 53p, 124n, 53e You may practice additional Questions from your etextbook on: Page 64 (3.1-3.6) Page 66 (3.7-3.8) Page 101 (4.3-4.6) Page 105 (4.7-4.13) Page 112 (4.25-4.31) Page 115 (4.33-4.44)
