This atomic model was the first to use quantum theory, in that the electrons were limited to specific orbits around the nucleus. Bohr used his model to explain the spectral lines of hydrogen.

Erwin Schrödinger

Erwin Schrödinger Following the atomic model of Niels Bohr and a thesis from de Broglie, Schrödinger articulated the movements of electrons in terms of wave mechanics as opposed to particle leaps. The Schrödinger Equation

STOP! Choice Ahead

A B This is really difficult learning ahead and I’m going to try my best to learn it. I’m not going to give up. This is really difficult and I’m going to quit as soon as I don’t know it. I’m going to check out completely or create issues for those choosing A.

Let’s try a water molecule. H 2 O When using Lewis Dot Structures, a single bond is represented with one line. O H H

Some helpful tools. Carbon can form a backbone or ring Hydrogens are on the outside The smaller number is usually on the inside Double or triple bonds can often form Copyright © 2024 SlideSpark .LLC Oxygen forms a double bond here.

Activity! Use the whiteboards to create Lewis Dot Structures for some common molecules.

Try Methane CH 4 Draw it and then build it Black = Carbon Yellow = Hydrogen

Now using electron dot diagrams Create molecules like Methane CH 4

Now using electron dot diagrams Create molecules like Methane CH 4 Carbon = Full Octet

Now using electron dot diagrams Create molecules like Methane CH 4 Carbon = Full Octet Hydrogen = Full Duet

Carbon Dioxide Gas CO 2 Hint- It forms a double bond. Double bonds occur when an atom isn’t completely involved. A difficult orbital thing that we aren’t going to cover. Copyright © 2024 SlideSpark .LLC

Carbon Dioxide Gas CO 2 Hint- It forms a double bond. Double bonds occur when an atom isn’t completely involved. A difficult orbital thing that we aren’t going to cover. Each oxygen will share 4 electrons with the carbon, Carbon then = 8 , and Oxygen =8  Copyright © 2024 SlideSpark .LLC

What Element are these?

Which one is essential for life?

Answer! Phosphorus (Part of DNA)

Which one is rat poison?

Answer! Arsenic

How are these two elements similar?

Answer! They both have 5 valence electrons?

Arsenic takes the place of Phosphorus in your DNA which causes death.

Make Glucose C 6 H 12 O 6 Black = Carbon Red = Oxygen Yellow = Hydrogen Note – Red should not touch another red, and it works easier if carbon is in a chain for building purposes. Copyright © 2024 SlideSpark .LLC
