Structure of an Atom Nucleus: Nucleus:Proton Nucleus:Proton+ Nucleus:Proton+ Neutron Nucleus:Proton+ Neutron No charge Structure of an Atom Nucleus:Proton+ Neutron No charge Outside the Nucleus: Structure of an Atom Nucleus:Proton+ Neutron No charge Outside the Nucleus: Electron Structure of an Atom Nucleus:Proton+ Neutron No charge Outside the Nucleus: Electron - Structure of an Atom Atomic Number - Structure of an Atom Atomic Number - The number of Protons in the nucleus Structure of an Atom Atomic Mass - Structure of an Atom Atomic Mass - The number of Protons plus the number of Neutrons in the nucleus Structure of an Atom Note: Note: On the Periodic Table Structure of an Atom Note: The number of Protons EQUALS the number Electrons in the atom On the Periodic Table Structure of an Atom Note: On the Periodic Table Structure of an Atom Note: ALL Elements on the Periodic Table are NEUTRAL On the Periodic Table Structure of an Atom Note: On the Periodic Table Structure of an Atom Note: The mass of an Element may change, but the Protons DO NOT! On the Periodic Table Structure of an Atom Question: Question: If the Protons stay the same, what is different to make the Mass change? Structure of an Atom Answer: Answer: Neutrons Role of Electrons Tiny Particles, Big Spaces Role of Electrons Tiny Particles, Big Spaces Valence Electrons: Role of Electrons Tiny Particles, Big Spaces Valence Electrons: Electrons farthest away from the Nucleus Role of Electrons Tiny Particles, Big Spaces Valence Electrons: Involved in bonding # of Valence Electrons Models of Atoms Dalton Model Models of Atoms Dalton Model Models of Atoms John Dalton Dalton Model Models of Atoms John Dalton Great Britain Dalton Model Models of Atoms John Dalton Great Britain 1808 Dalton Model 1808 Models of Atoms Dalton Model Each Element is made of small atoms.
