Physical and Chemical Properties
A property of a substance that can be observed or measured without changing the identity of the substance.
What is a physical property?
All matter is made up of these.
What are atoms?
If you rip a piece of paper in half, the paper has undergone this type of change.
What is a physical change?
The Periodic Table is made up of over 100 of these. They are considered the basic building blocks of matter.
What are elements?
What are the 3 states of matter?
What are Solids, Liquids and Gases?
A property of a substance that relates to how it chemically behaves.
What is a chemical property?
Negatively charged particles of an atom that float in clouds or shells around the nucleus.
What are electrons?
A metal rusting is an example of this type of change.
What is chemical change.
The horizontal rows going across the Periodic Table are called.
What are periods?
List the 3 particles that make up an atom.
What are protons, electrons, and neutrons?
The temperature at which a liquid becomes a gas. This is a physical property.
What is boiling point?
Protons are positively charged particles of an atom that are represented by this on the Periodic Table.
What is the atomic number?
The Statue of Liberty is made of copper and has turned to a greenish color overtime. In other words, the copper has tarnished. What type of change is this an example of?
What is a chemical change?
The columns of the Periodic table are called.
What are groups or families?
Describe how the molecules are different in solids, liquids, and gases.
In solids the molecules are packed tightly, in liquids they are free flowing, and in gases they are far apart.
Reactivity, flammability, the ability to oxidize, and toxicity are all examples of this type of property.
What is a chemical property?
The nucleus of an atom is made up of these two particles.
What are Protons and Neutrons?
Sugar dissolving in water is an example of this type of change.
What is physical change? No reaction has occurred.
The Periodic Table is arranged by this number that represents the number of protons and electrons.
What is atomic number?
All elements have different temperatures in which they change from a solid to a liquid or a liquid to a gas. What are these called? The noble gases typically have the lowest of these.
What are melting and boiling points?
The ability of a substance to be shaped or molded. An aluminum can has this physical property.
What is malleability?
The number of neutrons for an element can be calculated by subtracting these two numbers.
What is atomic mass minus atomic number?
Gas production, a color change, temperature change, the formation of precipitates, and change in odor are all indicators that this type of change has occurred.
What is a chemical change?
This group or family is considered to be the most stable because they have a full outer electron shell.
What are the noble gases?
This scientist was the first to organize elements based on properties and used this to explain the basic ingredients of matter. He also left blanks for other elements that were not yet discovered.
Who is Mendeleev?
