Question | Answer |
Continuous theory of matter | The theory that matter is not composed of tiny particles, but is just one blob |
Who proposed the Discontinuous Theory of Matter? | Democritus |
To understand something, you need to... | Break it down into all of its component parts |
Who is considered the founder of chemistry? | Antoine Lavoisier |
The Law of Mass Conservation | Matter cannot be created or destroyed; it can only change forms |
Element | Any substance that cannot be decomposed into less massive substances |
The jagged line in the periodic table separates | the metals from the non-metals |
Even though hydrogen is left of the jagged line | it is always considered a non-metal |
What are metalloids? | Elements that have both nonmetal properties and metal properties |
Compound | Substances that can be decomposed into elements by chemical means |
The Law of Definite Proportions | The proportion of elements in any compound is always the same |
The Law of Multiple Proportions | If two elements combine to form different compounds, the ratio of masses of the *second* element that react with a fixed mass of the *first* element will e a simple, whole-number ratio. |
Dalton's theory contained how many vital assumptions? | 4 |
What is the first assumption? | All elements are composed of small, indivisible particles called "atoms." |
What is the second assumption? | All atoms of the same element have exactly the same properties. |
What is the third assumption? | Atoms of different elements have different properties. |
What is the fourth assumption? | Compounds are formed when atoms are joined together. Since atoms are indivisible, they can only join together in simple, whole-number ratios |
An example of a chemical symbol is... | H, which stands for Hydrogen |
An example of a chemical formula is... | H2O, which stands for a water molecule |
Covalent compounds cannot | conduct electricity |
Ionic compounds can | conduct electricity |
A compound is ionic if it has... | at least one metal atom and at least one nonmetal atom |
A compound is covalent if it has... | only nonmetal atoms |
To name an ionic compound, you... | 1. Start with the name of the first atom in the molecule 2. Take the next atom in the molecule and the "ide" suffix 3. Put those two names together to get the name |
To name a covalent compound, you... | Do the same steps as with ionic, but add prefixes. |
