 Show 1/7 Organic Chemistry 1 Chapter 1 Structure and Bonding – Assignment/Quiz 1 1.Isotopes are atoms of the same element that have the same atomic number but a different mass number. This is because isotopes have the same number of protons but a different number of neutrons. 2.Which of the following statements correctly describe the general rule that governs chemicals bonding? Select all that apply. a.An atom will seek to attain the electron configuration of the nearest noble gas. b.An atom will bond so as to attain a complete valence shell. c.All elements on the periodic table will bond so as to attain a valence shell of eight electrons. Elements in the first row of the periodic table (e.g. hydrogen) cannot have eight valance electrons, and will bond so as to attain a valance shell of two electrons. d.Atoms will always share electrons in order to attain a complete valence shell. Atoms may gain, lose, or share electrons so as to attain a complete valence shell. 3.Match each type of bond to the correct description. Ionic bond – Electrons are transferred and the resulting species attract one another. Covalent bond – Electrons are shared between two nuclei. Ask most chemists who discovered the periodic table and you will almost certainly get the answer Dmitri Mendeleev. Certainly Mendeleev was the first to publish a version of the table that we would recognise today, but does he deserve all the credit? A number of other chemists before Mendeleev were investigating patterns in the properties of the elements that were known at the time. The earliest attempt to classify the elements was in 1789, when Antoine Lavoisier grouped the elements based on their properties into gases, non-metals, metals and earths. Several other attempts were made to group elements together over the coming decades. In 1829, Johann Döbereiner recognised triads of elements with chemically similar properties, such as lithium, sodium and potassium, and showed that the properties of the middle element could be predicted from the properties of the other two. It was not until a more accurate list of the atomic mass of the elements became available at a conference in Karlsruhe, Germany in 1860 that real progress was made towards the discovery of the modern periodic table. This area of the website celebrates the work of many famous scientists whose quest to learn more about the world we live in and the atoms that make up the things around us led to the periodic table as we know it today. {"ad_unit_id":"App_Resource_Sidebar_Upper","resource":{"id":28268435,"author_id":823458,"title":"Chemistry Chapter 1 Connect Homework","created_at":"2021-01-18T19:21:03Z","updated_at":"2021-01-22T17:38:05Z","sample":false,"description":"These connect homework questions are for the textbook \"Chemistry in Context, Applying Chemistry to Society\" 10th edition","alerts_enabled":true,"cached_tag_list":"chemistry, chemistry in context, mcgrawhill, mcgraw hill, 10thedition","deleted_at":null,"hidden":false,"average_rating":null,"demote":false,"private":false,"copyable":true,"score":65,"artificial_base_score":0,"recalculate_score":false,"profane":false,"hide_summary":false,"tag_list":["chemistry","chemistry in context","mcgrawhill","mcgraw hill","10thedition"],"admin_tag_list":[],"study_aid_type":"Quiz","show_path":"/quizzes/28268435","folder_id":1371425,"public_author":{"id":823458,"profile":{"name":"silverman.ana","about":null,"avatar_service":"gravatar","locale":"en-US","google_author_link":null,"user_type_id":156,"escaped_name":"Ana silverman","full_name":"Ana silverman","badge_classes":""}}},"width":300,"height":250,"rtype":"Quiz","rmode":"canonical","sizes":"[[[0, 0], [[300, 250]]]]","custom":[{"key":"rsubject","value":"History"},{"key":"rlevel","value":"College"},{"key":"env","value":"production"},{"key":"rtype","value":"Quiz"},{"key":"rmode","value":"canonical"},{"key":"sequence","value":1},{"key":"uauth","value":"f"},{"key":"uadmin","value":"f"},{"key":"ulang","value":"en"},{"key":"ucurrency","value":"usd"}]} {"ad_unit_id":"App_Resource_Sidebar_Lower","resource":{"id":28268435,"author_id":823458,"title":"Chemistry Chapter 1 Connect Homework","created_at":"2021-01-18T19:21:03Z","updated_at":"2021-01-22T17:38:05Z","sample":false,"description":"These connect homework questions are for the textbook \"Chemistry in Context, Applying Chemistry to Society\" 10th edition","alerts_enabled":true,"cached_tag_list":"chemistry, chemistry in context, mcgrawhill, mcgraw hill, 10thedition","deleted_at":null,"hidden":false,"average_rating":null,"demote":false,"private":false,"copyable":true,"score":65,"artificial_base_score":0,"recalculate_score":false,"profane":false,"hide_summary":false,"tag_list":["chemistry","chemistry in context","mcgrawhill","mcgraw hill","10thedition"],"admin_tag_list":[],"study_aid_type":"Quiz","show_path":"/quizzes/28268435","folder_id":1371425,"public_author":{"id":823458,"profile":{"name":"silverman.ana","about":null,"avatar_service":"gravatar","locale":"en-US","google_author_link":null,"user_type_id":156,"escaped_name":"Ana silverman","full_name":"Ana silverman","badge_classes":""}}},"width":300,"height":250,"rtype":"Quiz","rmode":"canonical","sizes":"[[[0, 0], [[300, 250]]]]","custom":[{"key":"rsubject","value":"History"},{"key":"rlevel","value":"College"},{"key":"env","value":"production"},{"key":"rtype","value":"Quiz"},{"key":"rmode","value":"canonical"},{"key":"sequence","value":1},{"key":"uauth","value":"f"},{"key":"uadmin","value":"f"},{"key":"ulang","value":"en"},{"key":"ucurrency","value":"usd"}]} {"ad_unit_id":"App_Resource_Leaderboard","width":728,"height":90,"rtype":"Quiz","rmode":"canonical","placement":2,"sizes":"[[[0, 0], [[970, 250], [970, 90], [728, 90]]]]","custom":[{"key":"env","value":"production"},{"key":"rtype","value":"Quiz"},{"key":"rmode","value":"canonical"},{"key":"placement","value":2},{"key":"sequence","value":1},{"key":"uauth","value":"f"},{"key":"uadmin","value":"f"},{"key":"ulang","value":"en"},{"key":"ucurrency","value":"usd"}]} Which of the following statement correctly describes the arrangement of elements in the periodic table?The non metals are above that staircase line and to the right to the right above last one says elements in the periodic table are arranged in order of increasing atomic mass.
Which is true about how the elements in the periodic table are arranged?In the modern periodic table, the elements are arranged according to their atomic number - not their relative atomic mass . In the periodic table the elements are arranged into: rows, called periods , in order of increasing atomic number. vertical columns, called groups , where the elements have similar properties.
Which statement is true of the elements in the same period in the periodic table?Like PERIODic table.). All of the elements in a period have the same number of atomic orbitals. For example, every element in the top row (the first period) has one orbital for its electrons.
How is the periodic table arranged quizlet?How is the modern periodic table organized? In the modern periodic table, elements are arranged by increasing atomic number (number of protons). Properties of elements repeat in a predictable way when atomic numbers are used to arrange elements into groups.
