Study Notes
Atomic Structure
- In Rutherford's Nuclear atomic model, the atom's mass is concentrated in the nucleus.
Chemical Bonding
- A metal and a nonmetal form an Ionic bond.
- Two non-metals form a Covalent bond.
Ions and Electronegativity
- A positively charged ion is called a Cation.
- A negatively charged ion is called an Anion.
- Electronegativity refers to the ability of an atom to attract electrons.
Hydrocarbons
- Alkane hydrocarbons have the ending -ane.
- Alkene hydrocarbons have the ending -ene.
- Alkyne hydrocarbons have the ending -yne.
Physics and Chemistry Principles
- Hund's Rule states that when filling orbitals of equal energy, electrons will occupy each orbital singly before pairing up.
- Electrons can absorb energy and move to an orbit with a higher energy level, a state known as Excitation.
- The Avogadro Constant represents the number of particles present in a mole of a substance.
Properties of Metals
- The property of metals that allows them to be shaped into flat sheets is known as Malleability.
