Electrons have negligible mass.<\/p>\n<\/details>\n<p><strong>Question 2: Is it true that atoms are divisible?<\/strong><\/p>\n<p>a) True<br \/>\nb) False<\/p>\n<details>\n<summary><strong>Answer:<\/strong><\/summary>\n<p>The correct answer is <strong>a) True.<\/strong><\/p>\n<p>Atoms are divisible because they consist of different particles like electrons, protons, and neutrons. The formation of ionic compounds involves the transfer of electrons, and isotopes exist due to the difference in neutrons.<\/p>\n<\/details>\n<p><strong>Question 3: According to Dalton&#8217;s atomic theory, matter is made up of<\/strong><\/p>\n<p>a) Molecules<br \/>\nb) Ions<br \/>\nc) Atoms<br \/>\nd) Mixtures<\/p>\n<details>\n<summary><strong>Answer:<\/strong><\/summary>\n<p>The correct answer is <strong>c) Atoms.<\/strong><\/p>\n<p>According to Dalton&#8217;s atomic theory, all matter, whether an element, a compound, or a mixture, is composed of small particles called atoms.<\/p>\n<\/details>\n<p><strong>Question 4: Is it true that atoms of different elements have different masses?<\/strong><\/p>\n<p>a) True<br \/>\nb) False<\/p>\n<details>\n<summary><strong>Answer:<\/strong><\/summary>\n<p>The correct answer is <strong>a) True.<\/strong><\/p>\n<p>Atoms of different elements have different masses because each subsequent element has an additional electron and proton, both of which contribute to the mass.<\/p>\n<\/details>\n<p><strong>Question 5: According to Dalton&#8217;s atomic theory, atoms are<\/strong><\/p>\n<p>a) Divisible<br \/>\nb) Indivisible<br \/>\nc) Heavier<br \/>\nd) Complex<\/p>\n<details>\n<summary><strong>Answer:<\/strong><\/summary>\n<p>The correct answer is <strong>b) Indivisible.<\/strong><\/p>\n<p>According to Dalton&#8217;s atomic theory, atoms are indivisible particles and cannot be created or destroyed in a chemical reaction. This was later disproven with the discovery of subatomic particles.<\/p>\n<\/details>\n<p><strong>Question 6: Which of the following is not a limitation of Dalton&#8217;s atomic theory?<\/strong><\/p>\n<p>a) The concept of isotopes was not considered.<br \/>\nb) It did not consider that atoms can be divided into subatomic particles.<br \/>\nc) It did not explain the law of chemical combination.<br \/>\nd) It did not consider the existence of isobars.<\/p>\n<details>\n<summary><strong>Answer:<\/strong><\/summary>\n<p>The correct answer is <strong>c) It did not explain the law of chemical combination.<\/strong><\/p>\n<p>Dalton&#8217;s theory could explain the laws of chemical combination. However, it failed to account for isotopes, isobars, and the divisibility of atoms.<\/p>\n<\/details>\n<p><strong>Question 7: Who proposed that an atom can neither be created nor be destroyed?<\/strong><\/p>\n<p>a) Ernest Rutherford<br \/>\nb) John Dalton<br \/>\nc) Neils Bohr<br \/>\nd) J. J. Thomson<\/p>\n<details>\n<summary><strong>Answer:<\/strong><\/summary>\n<p>The correct answer is <strong>b) John Dalton.<\/strong><\/p>\n<p>According to Dalton&#8217;s atomic theory, an atom is indivisible and indestructible, meaning it can neither be created nor destroyed.<\/p>\n<\/details>\n<p><strong>Question 8: Is it true that Dalton was unable to explain the concept of isobars and isotopes?<\/strong><\/p>\n<p>a) True<br \/>\nb) False<\/p>\n<details>\n<summary><strong>Answer:<\/strong><\/summary>\n<p>The correct answer is <strong>a) True.<\/strong><\/p>\n<p>Dalton\u2019s atomic theory stated that atoms of the same element are identical, but later discoveries revealed isotopes and isobars, which differ in mass and atomic number, respectively.<\/p>\n<\/details>\n<p><strong>Question 9: Which of the following was proposed by Dalton&#8217;s atomic theory?<\/strong><\/p>\n<p>a) Matter consists of divisible atoms<br \/>\nb) All atoms of a given element differ in their properties<br \/>\nc) Compounds are formed when atoms of the same element combine in a fixed ratio<br \/>\nd) Chemical reactions involve the reorganization of atoms<\/p>\n<details>\n<summary><strong>Answer:<\/strong><\/summary>\n<p>The correct answer is <strong>d) Chemical reactions involve the reorganization of atoms.<\/strong><\/p>\n<p>Dalton&#8217;s theory states that matter consists of indivisible atoms, and compounds are formed when atoms combine in a fixed ratio. During chemical reactions, atoms are reorganized, not created or destroyed.<\/p>\n<\/details>\n<p><strong>Question 10: According to Dalton\u2019s atomic theory, an atom can<\/strong><\/p>\n<p>a) Be created<br \/>\nb) Be destroyed<br \/>\nc) Neither be created nor destroyed<br \/>\nd) Be centrifuged<\/p>\n<details>\n<summary><strong>Answer:<\/strong><\/summary>\n<p>The correct answer is <strong>c) Neither be created nor destroyed.<\/strong><\/p>\n<p>Dalton&#8217;s atomic theory states that atoms are conserved during a chemical reaction; they are neither created nor destroyed.<\/p>\n<\/details>\n","protected":false},"excerpt":{"rendered":"<p>Class 9 Science Chapter 4 Structure Of The Atom Quiz 1 Are you ready to test your understanding of Class [&hellip;]<\/p>\n","protected":false},"author":53,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_yoast_wpseo_focuskw":"Structure Of The Atom quiz 1","_yoast_wpseo_title":"Quiz 1 Class 9 Science Chapter 4 Structure Of The Atom Quiz with Answers","_yoast_wpseo_metadesc":"Take Quiz 1 on Class 9 Science Chapter 4 Structure Of The Atom.
