Practice applying your understanding by playing the 3 rd and 4 th game levels. how the value of each letter is determined.Ī = element symbol b = charge c = atomic number d = atomic mass 9.Ĭreate a definition (using a complete sentence) for each of these items based on your labels from the atomic symbol above.Ī) Element Symbol a one or two letter abbreviation to represent the full name of the element b) Charge the difference between electrons and protons (+ has more protons, has more electrons, 0 has same of both) c) Atomic Number identifies the number of protons d) Mass Number identifies the number of protons and neutrons 10.the particle(s) used to determine the letter, and.a) In the atomic symbol below, label each letter ( a, b, c , and d) with:

Using the Symbol readout box, figure out which particles affect each component of the atomic symbol. If you do well on those first 2 levels, move on the 3rd and 4th level! Practice applying your understanding by playing 1 st and 2 nd levels on the Game screen (the tab at the top). a) What is a rule for determining the mass number of an atom or ion? Mass = the number of protons + the number of neutrons. Click on the green + sign next to Mass to reveal the balance, then continue to play the same way you were before. Play with the simulation to discover what affects the mass number of your atom or ion. The charge of an atom is determined by the ratio of protons to electrons. b) Develop a relationship (in the form of a single sentence or equation) that can predict the charge based on the number and types of particle. Negative ions have _ _fewer _protons than electrons. Positive ions have _ more _ protons than electrons. a) Fill in the blanks below to show your results: Neutral atoms have the same number of protons and electrons. What did you discover? Protons adding them moves from left to right on the Periodic Table What is the name of the following atoms? a) An atom with 3 protons and 4 neutrons: Lithium b) An atom with 2 protons and 4 neutrons: Heleum c) An atom with 4 protons and 4 neutrons: Beryllium Play with the simulation to discover which particles affect the charge of an atom or ion.

2.Įxplore the Build an Atom simulation with your group. As you explore, talk about what you find. Students may be interested in the even smaller particles of quantum physics-like quarks, bosons, neutrinos, and antineutrinos.ANSWER KEY : BUILD AN ATOM PART I: ATOM SCREEN Build an Atom simulation ( anatom ) 1. They are intended to get players thinking about what they already know about elements. General questions about the properties of elements assume standard temperature and pressure (helium is liquid below -268☌ and gold is a liquid above 1064 ☌). For this game, the most common isotopes of the chemical elements are used. This game presents a simple introduction to the Rutherford-Bohr model of the atom and the way we organize the elements.
