The study of matter, it's properties, and it's changes or transformations |
Chemistry |
|
Anything that has mass and takes up space. |
Matter |
|
This is a characteristic or description of a substance (including the state of matter at room temperature, hardness, melting and boiling points, solubility, etc) that can be used to identify it. |
Physical property |
|
This is the characteristic behavior that occurs when a substance interacts with one another to become a new substance. |
Chemical property |
|
This is when all the particles that make up the substance are the same (this type of substance has constant properties) |
Pure substance |
|
These are pure substances that cannot be broken down into simpler substances. |
Elements |
|
These are a type of pure substances that contain two or more different elements in a fixed proportion. |
Compounds |
|
This type of change is in the size or form of a substance, which does not change the chemical property of the substance |
Physical change |
|
This is the alteration of a substance into one or more different substances with different properties. |
Chemical change or reaction |
|
These are the starting materials in a chemical reaction. |
Reactant |
|
These are the substances produced in a chemical reaction |
Products |
|
This is a distinctive chemical reaction that can be used to identify an unknown substance |
Chemical test |
|
This gas is indicated by a lit splint bursting into flames. |
Oxygen gas |
|
This gas is indicated if the flaming splint "pops" |
Hydrogen (H2) |
|
This gas is indicated if line water turns milky |
Carbon Dioxide (CO2) |
|
This is a structured arrangement of elements |
Periodic table |
|
This is a substance that can conduct electricity when it is dissolved in water. |
Electrolyte |
|
This is a compound that does not conduct electricity |
Nonelectrolyte |
|
Located on the left side of the table |
Metals |
|
Located on the right side of the table |
Non-metals |
|
This is a charged atom in which the number of electrons is different from the number of protons |
Ion |
|
This is the numerical value of the electric charge with a plus or minus sign. |
Ionic charge |
|
These are formed by the addition of electrons to, or the removal of electrons from the atom. |
Ions |
|
The combination of two or more elements |
Molecules |
|
A molecular element has |
All atoms the same. |
|
This formula is the simplest whole number ratio of atoms in the compound. |
Empirical formula |
|
This is a chemical formula that indicates the number and type of atoms in one molecule |
A molecular formula |
|
These are compounds formed by the combination of two or more atoms held together by covalent bonds. |
Molecular compounds |
|
This is a bond formed by two or more non-metal atoms sharing one or more pairs of electrons |
Covalent bond |
|
This is the combining capacity of an element. |
Valence |
|
Is is a solid compound that contains water molecules as part of the solid crystalline structure. |
Hydrate |
|
Positively charged ions are called |
Cations |
|
Negatively charged ions are called |
Anions |
|
These are groups of elements in the same vertical column of the periodic table |
Chemical families |
|
The elements in the far left column of the periodic table are known as |
Alkali metals or group 1 |
|
Group 2 |
Alkaline earth metals |
|
Group 17 |
Halogens |
|
Group 18 |
Noble gases |
|
Three types of subatomic particles: |
Electrons, protons and neutrons |
|
These are heavily positively charged particles found in a dense positive core of the atom |
Protons |
|
These are neutral particles that have about the same mass as protons. |
Neutrons |
|
These are negatively charged particles with almost no mass that orbit the nucleus. |
Electrons |
|
The number of electrons in an atom must be equal to |
Protons |
|
These compounds are (metals +non-metals) and (metals + polyatomic ion) and named with the metal first then the nonmetal ending in -ide |
Ionic compounds |
|
This is a charged species composed of two or more atoms covalently bonded that acts as a single unit. |
Polyatomic ion |
|
These are compounds formed when hydrogen combines with polyatomic ions that contain oxygen. |
Oxyacids |
|
Metal + non-metal or metal + polyatomic ion = |
Ionic compounds |
|
Nonmetal + nonmetal or hydrogen + nonmetal = |
Covalent compounds |
