ASAP SCIENCE: science wars 3:37 mins) WELCOME TO SCIENCE! INTRO Alternative to the above slide. • Science STYLE –T-swizzle cover (asap science) 4:02 In this lesson: • Safety • Structure of an atom • Electron configuration • charge SAFETY Watch the video, list as many rules as you can from the video and why they are important. What makes up an atom? discuss Atoms, Molecules, Elements and compounds Atoms : The smallest building block (besides sub-atomic particles) Made up of a Nucleus (the centre) containing: • Protons (positively charged) • Neutrons (negatively charged). Moving around the nucleus, like the earth does to the sun are Electrons, with a negative charge. Proton Neutron Electron Think of an atom like a single brick of Lego, everything is built from that brick onwards. A ride that has only 2 seats can only hold 2 people. You cannot have 5 people in 2 seats. The is the same when we discuss the shells. Each shell has a capacity. Atoms Each shell can only hold a certain number of electrons. Shell 1- can only hold 2 electrons Shell 2 – can only hold 8 electron Shell 3- can only hold 8 electrons There are more than 3 shells. You will be only learning the first 3 shells (first 20 elements on the periodic table. THE PROCESS OF PLOTTING THE ELECTRONS INTO SHELLS IS CALLED ELECTRONIC CONFIGURATION Charge (play from 2:30) Electronic Configuration worksheet (OneNote under E Config. And bonding) Kahoot / Quizziz
