Science study guide
Terms in this set (26)
Describe the arrangement and movement of particles in a solid
particles are arranged tightly, and are packed. They can't move past each other, and can only vibrate
Describe the arrangement and movement of particles in a liquid.
Loosely packed, able to slide past eachother
Describe the arrangement and movement of particles in a gas
Spread out, zooming freely
What is condensation? Is energy added or removed?
When a substance changes from a gas to a liquid, heat is removed from the particles
What is evaporation? Is heat energy added or removed?
is the change from a liquid to a gas. Heat energy is added during this change.
What is sublimation? Is heat energy added or removed?
is the change from a solid to a gas. Heat energy's added during this this change
What is deposition? Is heat energy added or removed?
is the change from a gas to a solid. Heat energy is removed during the change.
What was the big idea that we discussed in class about the atomic theory?
as technology improved, so did the models of the atom.
What are the important features of Dalton's theory?
Atoms cannot be created divided or destroyed and atoms of the same are exactly alike.
What are the more important parts of JJ Thomson's theory?
that there were negatively charged particles called electrons floating around the atom. He said that atoms can be divided
What are the more important features in Ernest Rutherford's theory.
He discovered positively charged nucleus and Atoms are mostly empty space
What are the more important parts of Niels Bohr's theory?
electrons move outside the nucleus in energy levels. (Around positively charged nucleus)
What are the more important parts of the electronic cloud model?
This is the model closest to what we believe today. The location of electrons can only be predicted/estimated.
What is matter? Why is it so important? What is scientific proof that air is matter
is anything that occupies space and has a mass. It is important because it makes up everything in the universe. Air is matter because in the balloon lab we measured the mass of the balloon before and after inflation and saw there was a difference in the mess. This mass belonged to the air inside the balloon. We also tried to fit a balloon in a cup before and after inflation. Before inflation the balloon fit easily. After inflation the balloon did not fit because the volume had increased
What is an atom? How would you describe the size of an atom?
is a tiny piece of matter that makes up and is in everything. Hundreds of thousands of atoms could fit in a grain of sand.
Identify/name each part of a typical 'box' on the periodic table.
-Atomic number: tells you where the element is placed on the periodic table, and how many protons and electrons are in the element.
-Chemical symbol: The unique symbol on the periodic table for that element; used to build chemical formulas for molecules and compounds.
-Atomic mass: average mass of the Atom it's measured in AMU
What are the three subatomic particles,what are their charges, how can we find the amount of each, and where are they located?
proton, electrons, neutrons.
-Proton: located in the nucleus, positive charge, atomic number = the number of protons.
-Electron: located somewhere outside of the nucleus, negative charge, atomic number = number of electrons.
-Neutrons: located inside the nucleus, neutral charge, atomic mass - is atomic number = amount of neutrons.
Where are metals, non-metals and metalloids located on the Periodic Table?
Non-metals- Located to the right of the staircase
Metalloids- Located basically on the staircase
Metals- Located to the left of the staircase
What are the properties of metals?
Metals- Metals are shiny, they are good conductors of electricity, malleable and ductile. Most are solids at room temperature. Mercury is a liquid at room temperature.
What are the properties of non-metals?
Non-metals- Non-metals are not shiny, and are not good conductors of electricity. They are also not malleable or ductile. More than half are solids at room temperature.
What can we determine about the properties of metalloids?
We can determine that metalloids share properties of metals and nonmetals. Silicon - shiny like a metal but not a good conductor of electricity like non metals
What are columns on the periodic table called? What are rows called?
Columns are called groups or families and rows are called periods.
What is true about about elements that appear in the same group on the periodic table?
They will share similarities. (Same group on totem pole)
What happens to the properties of elements on the periodic table when they are arranged by their and wrapped into rows that stack into columns?
The properties of elements repeat when they are arranged by atomic number.
List examples of characteristic properties. When would knowing the characteristic properties of an element help you out?(what do they tell us)
characteristics that are true no matter what size or amount of a substance. Some are melting/boiling point, density, freezing point, solubility and magnetism. They are used to identify an unknown substance, and what it has in common with others
What is an element?
A form of matter that is made up of only one type of atom.
