Study Notes

Elements

  • Silver (Ag) is a pure element, consisting of one type of atom; found on the periodic table with its unique atomic number.
  • Gold (Au) is categorized as an element due to its single type of atom and presence on the periodic table.
  • Copper (Cu) is recognized as an element with one type of atom and a designated atomic number, appearing in items like pennies.
  • Helium (He) is an elemental gas found in balloons, characterized by a single type of atom and listed on the periodic table.
  • Aluminum (Al) is an element seen in foil, recognized for having only one type of atom.
  • Lithium (Li), found in batteries, is distinguished as an element; it possesses a unique atomic number among elements.
  • Mercury (Hg) is an element used in thermometers, consisting of one kind of atom without bonding.
  • Neon (Ne) is an elemental gas present in advertising signs, featuring only one type of atom.
  • Nickel (Ni), found in coins, qualifies as an element due to its atomic singularity and periodic table classification.
  • Iron (Fe) from nails is categorized as an element with just one type of atom and listed atomic number.

Compounds

  • Table Salt (NaCl) is a compound formed from the chemical bonding of sodium and chlorine, demonstrating the interaction of different atom types.
  • Sugar (C12H22O11) is identified as a compound, consisting of multiple types of atoms chemically bonded together.
  • Water (H2O) is a compound made up of hydrogen and oxygen atoms, chemically linked.
  • Liquid Bleach (NaClO) is a compound containing various types of atoms that are chemically bonded.
  • Baking Soda (NaHCO3) is classified as a compound owing to its composition of different atom types bonded together.
  • Marble (CaCO3) is recognized as a compound consisting of calcium, carbon, and oxygen atoms together.
  • Quartz (SiO2) is a compound that consists of silicon and oxygen atoms that are chemically bonded.

Mixtures

  • Salad is a mixture that includes various substances physically combined but not chemically bonded, allowing for easy separation of components.
  • Orange juice is a mixture of multiple substances that are combined without chemical bonding, easily separable.
  • Salt Water is known as a mixture, containing dissolved components that can be separated physically.
  • Chocolate chip cookies exemplify a mixture, as they consist of different ingredients combined without chemical bonding.
  • A sandwich is a mixture made of various ingredients that remain physically mixed but not chemically merged.
  • Kool Aid is a mixture of various scientific substances, intermingled but separable.
  • Air represents a mixture comprised of different gases that are physically mixed yet not chemically combined.
