1 Atomic Structure WALT – Explain what everything in the Universe is made of WILF – Diagram of atom structure in books

2 - Atoms - Elements - Molecules - Macromolecules - Cell organelles - Cells - Tissues - Organs - Systems - Organisms - Populations - Ecosystems - Biospheres - Planets - Planetary Systems with Stars - Galaxies - The Universe .And finish really big. .  You could start really small... - Particles of matter Wow. All of that is possible because of atoms

3 All atoms are made up of just 3 basic sub-atomic particles:-
Name: Proton. Mass: 1 Charge: +1 Name: Neutron. Mass: 1 Charge: 0 Name: Electron. Mass: 1/2000 Charge: -1 Draw in your books

4 Atomic Structure

5 H The Simplest Atom Name: Hydrogen Atomic Symbol: H
1 Atomic Number Mass Number The Simplest Atom Name: Hydrogen Atomic Symbol: H Mass Number (Number of Protons + Neutrons) = 1 Atomic Number (Number of Protons) = 1

6 He The Next Simplest Atom Name: Helium Atomic Symbol: He
4 2 Name: Helium Atomic Symbol: He The centre of an atom is called the NUCLEUS A Helium atom has two protons and two neutrons in its nucleus

7 Electron Configuration: 2,1
The Next Simplest Atom Li 7 3 Name: Lithium Atomic Symbol: Li The orbit nearest the nucleus can only contain 2 electrons so the third electron must be in a new orbit. Electron Configuration: 2,1

8 Be The Next Simplest Atom Name: Beryllium Atomic Symbol: Be This orbit
9 4 Name: Beryllium Atomic Symbol: Be This orbit has room for 8 electrons Electron Configuration: 2,2

9 B The Next Simplest Atom Name: Boron Atomic Symbol: B 5p 6n
11 5 Name: Boron Atomic Symbol: B 5p 6n Electron Configuration: 2,3

10 Pg 122 – Answer questions 1-4 – Finish for h/w

11 For the next 13 elements (Carbon to Argon)
draw their atomic structure and give atomic number

12 WILF – Diagrams of all 20 in books
WALT - Compare the structures of the first twenty elements of the Periodic Table WILF – Diagrams of all 20 in books Arrange the first 20 elements with atomic (proton) numbers into a simple Periodic Table A game of cards involving atomic structure
