    Gizmos Name: Gab Talavera | Date Student Exploration: Electron Configuration Directions: Follow the instructions to go through the simulation. Respond to the questions and prompts in the orange boxes. Vocabulary: atomic number, alomic radius. Aufbau principle, chemical family, diagonal rule, electron configuration. Hund s rule, orbital. Pauli exclusion principle, period, shell, spin, subshell Prior Knowledge Questions (Do these BEFORE using lhe Gizmo.) 1. Elvis Perkins, a ralher shy fellow, is gelling on lhe bus shown al right Which seat do you think he will probably sit in? F.1ark this seal with an "E." Elvis will probably sit in the top let! seat 2. Marta Warren gets on lhe bus after Elvis. She is lired after a long day at work. Where do you think she will sit? Mark this seat with an "M." I think Marta will sil in lhe seat closest to lhe driver. 3. In your experience, do strangers gelling on a bus like to sil with olher people if there is an empty seat available? No. they sit in the empty seats if they are available. If nol, they are forced to sit beside a siranger. Gizmo Warm-up Just like passengers getting on a bus. electrons orbit the nuclei of atoms in particular patterns. You will discover these patterns (and how electrons sometimes act like passengers boarding a bus) with the Etecfron Configuref/on Gizmo. To begin, check that Lithium is selected on lhe PERIODIC TAEiLE tab. ■■ 1. The atomic number is equal to the number of protons in an atom. *** How many protons are in a lithium atom? t 3 • B > 7 ■ 34 Tl V Ci Mn F l I 3 protons are in a lithium atom. Y Zf Ifc MS TC P l I 2. A neutral atom has the same number of electrons and protons. How many electrons are in a neutral lithium atom? 3 electrons in a neutral lithium atom. 3. Select the ELECTRON CONFIGURATION lab. and check that Energy is selected. Click twice in lhe 1s box at lower left and once in the 2s box. Observe the atom model at right. A. Wh al do you see? I see 2 electrons spinning close to lhe nucleus and 1 electron spinning far. B Click Check . Is this electron configuration correct? Yes. lhe electron configuration is correct.

    Get lhe Gizmo ready: 1 Activity A: • On the PERIODIC TABLE lab : select H (hydrogen). 1 H 2 Small atoms • Select the ELECTRON CONFIGURATION tab. • Click Reset 2 LI Be Introduction: Electrons are arranged in orbitals subshells and shells. These levels of organization are shown by lhe boxes of the Gizmo. Each box represents an orbital. The subshells are labeled with letters (s, p, d. and I) and lhe shells are labeled wilh numbers. Question: How are electrons arranged in elements with atomic numbers 1 through 10? 1. Arrange: The Aufbau principle slates that electrons occupy the lowest-energy orbital. When Energy is selected the orbitals are arranged from lowest-energy al the bottcm Io highesl-energy at the top. Click once in the 1 s box to add an electron to lhe only orbital in lhe s subshell of the first shell. Click Check. What is the electron configuration of hydrogen? 1s 2. Arrange: Click Next element to select helium. Add another electron Io the 1s orbital. The arrows represent lhe spin of lhe electron. What do you notice about the arrows? I notice lhat one arrow goes up and lhe olher one goes down. The Pauli exclusion principle states lhat electrons sharing an orbital have opposite spins. 1s 2 3. Check your work: Click Check. What is the electron configuration of helium? 4. Arrange: Click Next element and create electron configurations for lithium, beryllium, and boron. Click Check Io check your work, and then list each configuration below: Is s 1 Beryllium: 1s 2 2s 2 Boron: 1s 2 2s 2 2p 1 5. Arrange: Click Next element to select carbon. Add a second electron Io the firsl 2p orbital Click Check . What feedback is given? Electrons are nol properly arranged in energy levels. 6. Rearrange: Hund's rule states th al electrons will occupy an empty orbital when it is available in that subshell. Rearrange lhe electrons within the 2p subshell and click Check. 20 I I? Is the configuration correct now? Yes u ~ Show the correct configuration in the boxes al right: Hand draw in this space orclick here Io select EDIT to use the drawing tool

    7. Compare: How are the electrons in the 2p subshell similar to passengers getting on a bus? The electrons are occupying other 2p sutoshells like bus seats. 8. Practice: In the spaces below, write and illustrate electron configurations for the next four elements: nitrogen, oxygen, fluorine, and neon. When you are finished, use the Gizmo to check your work. Correct any improper configurations. Nitrogen configuration: 1s 2 2s 2 2p : St is t 2p □ [n □ Oxygen configuration: 1s 2 2s 2 2p* n is T £ 2p E U □ Fluorine configuration: 1s 3 2s 2 2p 5 Si 1i * l 2p • d t 1 Neon configuration: 1s 2 2s ; 2p e Si is 77 t 1 2p T J 77] 9. Apply: Atoms are most stable when their outermost shell is full. If their outermost shell is not full, atoms tend Io gain. lose, or share electrons until the shell fills up. While doing this atoms react and form chemical bonds with other atoms. Based on this, what can you infer about the reactivity of helium and neon? I can infer from the reactivity of helium and neon that they are stable since they are noble gasses. 10. hink and discuss: Select the PERIODIC TABLE tab and look al the second row. or period, of the table. How does this row reflect the subshells of the second shell? This row reflects that there are 2 subshells in this row.
