Slide 11: Atomic Structure
Atomic Structure Parts of an atom (sub-atomic particles) Atoms are so, so, small that we can’t see them with our eyes. Not even with a magnifying glass! 11
Slide 12: Atomic Structure
Atomic Structure Parts of an atom (sub-atomic particles) Different combinations of the sub-atomic particles combine to make all the unique elements (atoms) Nucleus Nucleus Proton Electrons Neutron - Protons Electron Neutrons 12
Slide 13: Atomic Structure
Atomic Structure Parts of an atom (sub-atomic particles) Different combinations of the sub-atomic particles combine to make all the unique elements (atoms) Nucleus Nucleus Electrons • Positive charge - from Proton(s) • Center of the Atom - • Houses Protons and Neutrons Protons Neutrons 13
Slide 14: Atomic Structure
Atomic Structure Parts of an atom (sub-atomic particles) Different combinations of the sub-atomic particles combine to make all the unique elements (atoms) Nucleus Proton Electrons • Positive charge (+) • Number of protons is unique to every atom - • Greek word: “First” Protons Neutrons 14

Slide 19: Periodic Table of the Elements
Periodic Table of the Elements Elements is another term for atoms • Table initially designed in 1869 by scientist Dmitri Mendeleyev. • Elements are identified by their symbols (example: O for oxygen) • Each element has their own cell with the following information: • Atomic Number • Atomic Symbol 1
Slide 20: A look at the Sodium atom
A look at the Sodium atom Atomic Number 11 Na Na Atomic Symbol Sodium Name Sodium 22.99 (23) Atomic Mass 22.99 (23) Atomic Number = Number of Protons = 11 Atomic Mass - Atomic Number = Number of Neutrons 23 - 11 = 12 Number of Protons = Number of Electrons = 11 20
