Study Notes
Matter and Its Properties
- Matter is defined as anything that has mass and takes up space.
- Natural gas is an example of matter.
- Clouds are an example of matter.
- A rock is an example of matter.
- Density is a physical property.
- Corrosiveness is a chemical property.
- Boiling point is a physical property.
- Mass is a physical property.
- Oxidizer is a chemical property.
- A property of an object being fuzzy is a physical property.
- Ductility is a physical property.
Density
- If two objects have the same volume but one has a greater mass, the one with the greater mass has a higher density.
- Density is calculated as mass divided by volume.
- The density of alcohol is less than the density of water.
- The densities of substances of the same material can vary if the mass and volume vary.
Laboratory Equipment
- Using a meter stick can measure the length of a lab table.
- Grams are used to measure mass.
Density Calculation Example
- A piece of wood with a mass of 25.0 g and a volume of 29.4 cm³ has a density of 0.85 g/cm³.
- A piece of wood measuring 3.0 cm by 6.0 cm by 4.0 cm with a mass of 80.0 g has a density of 1.06 g/cm³.
Laboratory Equipment Choice
- A meter stick is the correct tool to measure the length of a lab table.
- A balance is used to measure mass.
Length Measurement
- The length of a piece of paper is 1.36 cm.
Periodic Table
- Carbon is in Group IVA.
- Tin is in Period 5.
- Elements in Group 6A (VIA) include Tellurium, Selenium, and Oxygen.
- Thallium, Neon, Strontium, and Bromine are either a metal, nonmetal, or metalloid
Elements and Metals
- Metals typically have luster, ductility, and conductivity.
- Nonmetals are often dull, brittle, and poor conductors.
- Metalloids show characteristics of both metals and nonmetals.
- Metals typically have high melting points, are reactive with acids, and often have a characteristic luster.
Subatomic Particles
- Protons and neutrons are located in the nucleus of an atom and have a relative mass of approximately 1 amu.
- Electrons orbit around the nucleus.
- Electrons have a negative charge.
- Protons have a positive charge and are inside the nucleus.
- Neutrons have no charge and are inside the nucleus
Atomic Number
- The atomic number of an atom is equal to the number of protons in the atom's nucleus.
- Nickel's atomic number is 28.
- Potassium has 19 protons.
- The mass number is the sum of protons and neutrons.
Isotopes
- Isotopes of an element have the same number of protons but different numbers of neutrons.
Ionic Bonding
- Ionic compounds are formed when a metal loses electrons to a nonmetal to achieve a stable electron configuration (octet rule).
Covalent Bonding
- Covalent compounds are formed when two nonmetals share electrons to achieve a stable electron configuration.
Naming Ionic Compounds
- Use prefixes to indicate the number of each element in covalent compounds.
Polyatomic Ions
- Use the correct formula for polyatomic ions to name and write formulas of compounds. For example, carbonate is CO3-2 which is used in barium carbonate with the formula BaCO3
