Atoms

• A Particle with an equal amount of protons and electrons

Proton

• Positively charged particle in nucleus

Electron

• Negatively charged particle outside of the Nucleus
• Approximately 1000x smaller than protons
• Extremely mobile because of their size

<aside> 💡

When the number of protons are unequal to the number of electrons, then the atom is called an ion

Electrostatic Forces

• Charges attract/repel based on their “identity”

<aside> 💡 Called Electrostatic Attraction or Repulsion

</aside>

Coulomb’s Law

• Attraction or Repulsion is proportional to the charge and distance
• Big Charge = Big attraction
• Big Distance = Little attraction

<aside> 💡 $Attraction = Charge/Distance$

Orbitals

• Electrons exist in space called orbitals
