Periodic Table
What are the electrons on the outermost shell called?
What are valence electrons
These are good conductors of heat and electricity?
What are metals
What is the heat transfer that occurs only in solids and only through direct contact?
What is conduction
Temperature is the measure of what?
What is kinetic energy (or how fast particles are moving)
What cannot happen to energy?
How is the periodic table arranged?
What is increasing atomic number?
This rule states that atoms tend to achieve 8 valence electrons?
What is the octet rule
This heat transfer only occurs through fluids, and is a movement of heat rather than a transfer
What is convection
Heat is a transfer of energy from warmer to cooler or cooler to warmer places?
Rubbing your hands together to keep warm is an example of what TRANSFORMATION of energy? Needs 2 types
What does each new period (row) on the periodic table represent?
What is a new electron shell?
What 2 elements on the periodic table aim to achieve 2 valence electrons, and not 8?
What are hydrogen and helium
This type of heat transfer occurs in a vacuum
What is radiation
True or false: 2 items of the same substance but different masses can have the same temperature?
True
Using a solar panel for power is an example of what TRANSFORMATION of energy?
What is light to electrical
Which group of elements have a completely filled electron shells, causing them to be unreactive?
What is group 18, or the noble gases?
True or false: The atoms in period 18 are typically larger than the atoms in group 1?
False
In convection, the hotter particles near the heat source will become less dense and... (float, sink)
What is float
True or false: 2 items of the same substance but different masses can have the same amount of energy?
False
An increase in temperature means an increase in what type of energy?
What is kinetic energy
What characteristic causes elements to have similar chemical properties?
What is the same group/ same number of valence electrons?
How many electron shells would be found on the atoms in period 2?
What is 2 electron shells
This is a heat transfer through electromagnetic waves?
Increasing the reactants in a chemical reaction will cause what to occur?
The reaction will occur faster because there are more particles to make collisions
What is an example of chemical energy?
