Slide 1 : Atomic Structure 100’s of free ppt’s from www.pptpoint.com library
Slide 2 : All atoms are made up of just 3 basic sub-atomic particles:-
Slide 3 : The Simplest Atom Name: Hydrogen Atomic Symbol: H Atomic Number (Number of Protons) = 1 Mass Number (Number of Protons + Neutrons) = 1
Slide 4 : The Next Simplest Atom 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
Slide 5 : The Next Simplest Atom Name: Lithium Atomic Symbol: Li Electron Configuration: 2,1 The orbit nearest the nucleus can only contain 2 electrons so the third electron must be in a new orbit.
Slide 6 : The Next Simplest Atom Name: Beryllium Atomic Symbol: Be Electron Configuration: 2,2
Slide 7 : The Next Simplest Atom Name: Boron Atomic Symbol: B Electron Configuration: 2,3
Slide 8 : For the next 13 elements (Carbon to Argon)
draw their atomic structure and give details
as for Boron.
