Day 3:ATOMIC STRUCTURE

Atom Builder Simulation

Atomic Structure

All matter is made of atoms! They are the tiniest building blocks of the universe. So what are atoms made of? Explore the activities to the right to learn more about atomic structure- Start with the top right information on atomic structure - Move Clockwise to finish with the Atom Builder Simulation - When you're ALL done, click the center of the atom (the nucleus)

Fill in the blanks

Electrons

Reading the Periodic Table (Youtube)

About Electrons

Electrons are the negative parts of the atom. They have no mass/weight, which is why they don't contribute to the atomic number.

Electrons...

  • Circulate the nucleus
  • In a pattern not fully understood but,
  • It's best described as an orbit around the nucleus or
  • A hazy cloud of electrons

Day 3 Done!!

Congratulations! You completed this 3-day lesson on the Properties and Structures of Matter. I hope you learned a lot and had fun. I certainly had fun making this for you all.

To officially wrap up, pick ANY element on the periodic table and post 2 facts about it in our JamBoard

Structure of the Atom

At the center of all atoms is a NucleusThe Nucleus has - Neutrons (neutral, have no charge) -Protons (positive, have positive charge)

The number of protons and neutrons an atom has determines how much it weighs and what element number it is- Carbon has 6 protons and 6 neutrons, so it is element number 12! Learn more about electrons in the next activities

Open the PhET Simulation Below

Start with the "Symbol" tab to explore the different atoms you can make by adding protons, neutrons, and electrons

  • Take note of anything you notice that we haven't talked about yet
  • Feel free to try the Atom or Games modes
