Experiment with the atom builder and build 4 different atoms. To build an atom, click and drag protons, neutrons, and electrons and place them into the atom. Then click the button next to Net Charge and Mass Number to open both of those windows. Procedure: In the atom building simulator, select the first choice labeled 'Atom'. (Example: predict that adding more neutrons will affect.) What did you discover What is the name of the following atoms a) An atom with 3 protons and 4 neutrons. b) What particle(s) are found in the center of the atom Play until you discover which particle(s) determine(s) the name of the element you build. Hypothesis: Predict how the addition of subatomic particles will affect the structure and properties of an atom. a) List two things you observed in the simulation. What particles are atoms composed of? Protons, neutrons, and electrons.

Who were some of the scientists involved in discovering the atom? Dalton, Rutherford. Introduction: What is an atom? An atom is the smallest unit of ordinary matter that forms a chemical element. Is it stable or unstable? Identify the element. What is in your nucleus? Capture and paste an image. Fill in the table to identify three examples (at least 1 stable and at least 1 unstable) that show how your rules for stability work to 'build an atom' of your own.Ĥ. This is a modified version of the activity created by Timoty Herzog and Emily Moor. Build an Atom PhET Simulation Answer Key.pdf - 1527 kB. What seems to make the center of the atom unstable?ģ. CP 17 Lab 2 Build an Atom PhET Simulation.docx - 185 kB. Explore until you discover a good rule for making the center of the atom stable. What parts go in the center of the atom? What is the center called?Ģ. Open the Atom screen and explore to develop your own ideas about the atomic particles that make up atoms and ions.ġ. Part 1 Directions: Use your own words and captured images for each question. Draw the symbol for the element as it would appear on the periodic table. Use a periodic symbol to indicate the number of protons, neutrons, and electrons in an atom or ion. Describe all vocabulary words needed to meet the goals. Predict how the addition or subtraction of a proton, neutron, or electron will change the element, the charge, and the mass of the atom or ion. Determine if the model is for a neutral atom or an ion. Use given information about subatomic particles to identify an element and its position on the periodic table. Students will be able to make atom models that show stable atoms or ions. Explore the Build an Atom simulation with your group. This lab uses the Build an Atom simulation from PhET Interactive Simulations at the University of Colorado Boulder, under the CC-BY 4.0 license: ANSWER KEY : BUILD AN ATOM PART I: ATOM SCREEN Build an Atom simulation ( ) 1. This is their first introduction to the concept of subatomic particles and the structure of an atom.Build an Atom Remote Lab (This lesson is designed for a student working remotely) English Deutsch Français Español Português Italiano Român Nederlands Latina Dansk Svenska Norsk Magyar Bahasa Indonesia Türkçe Suomi Latvian Lithuanian esk. They have learned that atoms themselves are made up of even smaller particles, but not what these subatomic particles are. The students have already learned about elements and the periodic table and that all elements are made up of atoms. This activity was created for a combined 8th-grade physical science and technology class on a remote-learning day to be taught using a Zoom meeting. Study with Quizlet and memorize flashcards containing terms like What particles are located in the center of an atom, What do the number of protons. The objective is: I can use a computer simulation to develop a model of atomic structure. This is a simple, inquiry-based activity using the PhET Build an Atom simulation.
