The Bachelor: Atom edition
Atoms are lonely hearts that are constantly in search of partners to bring stability to their lives. Your job is to play matchmaker and make each atom stable by determining how many valence electrons each element needs and finding a partner that will complete the valence energy level. What information do you need to complete this task?
Atoms are lonely hearts that are constantly in search of partners to bring stability to their lives. Your job is to play matchmaker and make each atom stable by determining how many valence electrons each element needs and finding a partner that will complete the valence energy level.Octet Rule:8 electrons in outermost energy level=be like noble gas!
Based on what you know already, make a hypothesis! If an element has -------------------------------------, then it will be -------------------------- because -----------------------------------------------------------------------------------
Let’s meet our first bachelor, Mr. Sodium. Mr. Sodium is very lustrous but has an explosive personality when he gets near water or oxygen. He is quite a lonely metal that, like all metals, is looking to lose a few electrons! Since he is highly reactive… so be careful with who you pick to be his date! 11 Na Sodium 23
Let’s meet our eligible bachelorettes: 3Li Lithium 7 20 Ca Calcium 40 9 F Fluorine 19 Who should Mr. Sodium date?
Let’s meet our next available bachelor, Mr. Magnesium. Mr. Magnesium is a lonely metal who, like all metals, is looking to lose a few electrons! While he is needed by many living things, he is having a hard time finding love. 12 Mg Magnesium 24
Let’s meet our eligible bachelorettes: 10Ne Neon 20 8 O Oxygen 16 15 P Phosphorous 31 Who should Mr. Magnesium date?
All the couples you have made so far have special name called IONIC COMPOUNDS.The forces of attraction that bind these oppositely charged ions is called ionic bondingCation lose electron and the examples are Mg & Na (metals). Anion gain electron and the examples are F, Ne, O, F (nonmetals)
Let’s practice writing electron configuration for cations and anions.F-Charge?Number of protons?Number of electrons?Electron configuration? Try it on your own! b) Ca2+ C) Na+ d) O2-
*Filling orbitals to visually see how electrons are distributed is nice…but it takes too much space and time to draw it out, right? So from now on, use Lewis Dot Structure to indicate valence electron.*How to make Lewis dot structure?Figure out how many valence electron the element hasUse dots to put it around the element.
