Structure of an Atom - Coggle Diagram
Structure of an Atom
Electron Cloud
Only Electrons
Outside the Nucleus
The area electrons are most likely to be found
Atoms are mostly Empty Space
Electron Orbitals
S, P, D, and F Blocks
2 Electrons Max per orbital
Electrons want to be far from each other
Principles
Aufbau Principle
Pauli Exclusion Principle
Hund's Rule
Electrons
Negative Charge
Electrons > Protons
Little to no mass
Outside Nucleus
Equal to p in neutral atom
Ions
Difference in number of electrons
Either positively or negatively charged
Anion
Negative Ion
Atom gains electrons
Cation
Positive Ion
Atom loses electrons
Nucleus
Protons
Inside the Nucleus
Equal to Mass Number
Part of Mass Number
Defines Element
Positive Charge
Mass Number
Protons + neutrons
Isotopes
Difference in the Number of neutrons
Mass of the atom
Atomic Mass
Calculated average Mass taking into account abundance and isotopes
Positive Charge
Protons have a positive charge
Atoms have a positive charge when protons > electrons
Atomic Number
Determines the atom’s element
Equal to the number of protons
Also equal to # of electrons if atom is neutral
Neutrons
Inside the Nucleus
Difference in neutrons = Isotopes
Part of Mass Number
Neutral Charge
Neutral
Neutrons have a neutral charge
Atoms are neutral when protons = electrons
Center of the Atom
Made of Protons and Neutrons
Almost all Mass of the atom
