Questions and Answers

Match the definitions with the correct terms related to matter:

Matter = Anything that occupies space and has mass Atom = Smallest unit of a chemical element Vacuum = Volume of space without any matter Atomic Theory = Theory explaining the composition of matter

Match the ancient scholars with their contributions to the study of atoms:

Democritus = Proposed the idea that matter is made of indivisible particles John Dalton = Developed the Atomic Theory based on scientific laws Aristotle = Believed in four elements; did not accept atomic theory Lavoisier = Formulated the Law of Conservation of Mass

Match the components of an atom with their descriptions:

Proton = Positively charged particle in the nucleus Neutron = Neutral particle in the nucleus Electron = Negatively charged particle orbiting the nucleus Nucleus = Center of the atom containing protons and neutrons

Match the types of matter with their classifications:

Pure Substance = Matter with a constant composition Mixture = Combination of two or more substances Element = Substance that cannot be broken down chemically Compound = Substance formed from two or more elements chemically bonded Signup and view all the answers

Match the scientific laws with their relevance to atomic theory:

Law of Conservation of Mass = Mass is neither created nor destroyed in chemical reactions Law of Constant Composition = A compound always contains the same proportion of elements Law of Multiple Proportions = When elements combine, they do so in fixed ratios Ideal Gas Law = Relates the volume, temperature, and pressure of gases Signup and view all the answers

Match the following assumptions of atomic theory with their descriptions:

A = Atoms are composed of extremely small particles. B = All atoms of a given element are identical. C = Atoms cannot change into different elements through chemical reactions. D = Compounds have the same relative number and kind of atoms. Signup and view all the answers
