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.
- Examples of matter include clouds and rocks.
- Examples of things that are not matter include sound, electricity, and X-rays.
- Density is a physical property.
- Corrosive, boiling point, oxidizer, mass, poisonous, and ductile are also physical properties.
- If two objects have the same volume but one has a greater mass, the one with greater mass has a higher density.
- Alcohol is less dense than water. If you measure the mass of the same volume of alcohol and water, the water would have a greater mass.
- The densities of substances of the same material can vary if mass and volume vary.
Density
- Density is calculated by dividing mass by volume (D=m/v)
- Density is expressed in g/cm³.
- If two objects have the same volume, the denser object has a greater mass.
Laboratory Equipment
- A meter stick is used to measure length.
- Grams are used to measure mass.
Periodic Table
- Carbon is in Group IVA.
- Tin is in Period 5.
- Elements in Group 6A (VIA) include tellurium, selenium, and oxygen.
- Thallium is a metal.
- Neon is a non-metal.
- Strontium is a metal.
- Tellurium is a metalloid.
- Sodium is a metal
- Bromine is a non-metal.
Metals and Nonmetals
- Metals typically have a shiny luster, are ductile, and are good conductors of heat and electricity.
- Nonmetals typically lack luster, are brittle, and are poor conductors of heat and electricity.
- Metalloids have properties intermediate between those of metals and nonmetals. Their properties can vary.
Atomic Structure
- Protons and neutrons are found in the nucleus of an atom.
- Electrons orbit the nucleus.
- Protons have a positive charge.
- Neutrons have no charge.
- Electrons have a negative charge.
Subatomic Particles
- Protons and neutrons have a relative mass of approximately 1 amu.
- Electrons have a negligible mass.
- Electrons have a negative charge.
Atomic Number
- Atomic number of potassium is 19.
Atomic Mass
- Mass number of an element is calculated by adding the number of protons and neutrons.
Isotopes
- Isotopes are atoms of the same element that have different numbers of neutrons.
Ionic Bonding
- Ionic bonds form when electrons are transferred from one atom to another.
- The result is positive and negative Ions that attract .
- Atoms are more stable when they have a full valence shell.
- Ionic bonds occur between a metal and a non-metal.
Nomenclature
- For naming binary ionic compounds, the cation is named first, followed by the anion.
- For naming covalent compounds, prefixes are used to indicate the number of atoms of each element in the compound.
Covalent Bonds
- Covalent bonds form when electrons are shared between atoms.
- Covalent bonds occur between nonmetals.
