![]() The symbol is the same as the first letter of the element. 2 BUILD AN ATOMī) Each representation (Symbol and Name) in the table above provides information about the atom. Describe the similarities and differences between the Symbol and Name representations. In addition to atomic symbol, we can represent atoms by name and mass number. Play until you can get all the questions correct on the 4 th level. 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. Adding electrons you can only add 2 to the first orbital and 8 to the secondī) What particle(s) are found in the center of the atom? Protons and neutrons Play until you discover which particle(s) determine(s) the name of the element you build.Adding electrons will change it from a +ion to neutral atom, to ion depending on how many electrons you add.You can get the atom to be stable/unstable by adjusting the number of neutrons.Adding protons changes the identity of the atom adding one moves from right to left on the Periodic Table.Responses will vary, but here is what you should see…. a) List two things your group observed in the simulation. 2.Įxplore the Build an Atom simulation with your group. As you explore, talk about what you find. They are also all listed on TPT if you prefer buying that way.ANSWER KEY : BUILD AN ATOM PART I: ATOM SCREEN Build an Atom simulation ( anatom ) 1. It goes great with the Periodic Table Battleship game we created, too! Also check out this post on how to Teach Chemistry to Kids. The printable cards include the following elements: ![]() We loved this fun interactive chemistry lesson! When you have multiple rings for the orbits, make some a little smaller than others so you can layer them. ![]() Just add the needed number of beads onto the pipe cleaner and twist it together. We used Pipe Cleaners for the orbits, Pony Beads for the electrons and Pom Poms for the nucleus of our atomic models. The atomic number of the elements represents the number of electrons the element has. The Bohr Atomic model has a positively charged atomic nucleus with negatively charged electrons circling the nucleus on orbits (the circular lines).
