Study Notes
- Atoms are the smallest particle of a chemical element that can exist.
- Elements are substances composed of a single type of atom.
- Atoms consist of protons, neutrons, and electrons.
- Isotopes are atoms with the same proton number but different neutron numbers.
- The periodic table summarizes all chemical elements and provides information about their atomic structure.
- Electrons are held in shells around the nucleus, and each shell has a maximum number of electrons it can hold.
- Atoms react with each other to achieve a full outer shell of electrons.
- Chemical bonding includes ionic bonds, covalent bonds, and metallic bonds.
- Macromolecules are giant structures made of millions of atoms joined by covalent bonding.
- Diamond, graphite, and silicon dioxide are examples of macromolecules.
- Diamond is a crystalline form of carbon with a 3D structure.
- Graphite is another form of carbon with a layered structure.
- Graphite has a "sea of electrons" that holds its layers together.
- Silicon (IV) oxide has a structure similar to diamond and quartz exists as colorless crystals.
- Quartz has properties similar to diamond, including high hardness and a high melting point.
- Metallic bonding involves cations surrounded by a sea of electrons.
- The sea of electrons in metallic bonding holds the lattice structure of cations together.
- Metallic bonding is defined as the electrostatic forces between cations and their surrounding electrons.
- Diamond and quartz are hard and do not conduct electricity.
- Metallic bonding is responsible for the properties of metals.
