Name: Proton. Mass: 1Charge: +1 Name: Neutron. Mass: 1Charge: 0 Name: Electron. Mass: 1/2000Charge: -1 All atoms are made up of just 3 basic sub-atomic particles:-
3
The Simplest Atom Name: Hydrogen Atomic Symbol: H Atomic Number (Number of Protons) = 1 Mass Number (Number of Protons + Neutrons) = 1 H 1 1 Atomic Number Mass Number
4
The Next Simplest Atom 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
5
The Next Simplest Atom Li 7 3 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.
6
The Next Simplest Atom Be 9 4 Name: Beryllium Atomic Symbol: Be Electron Configuration: 2,2 This orbit has room for 8 electrons
7
The Next Simplest Atom B 11 5 Name: Boron Atomic Symbol: B Electron Configuration: 2,3 5p6n
