Unit 1 Matter
What is the solid state
The unit used to measure energy.
What is the joule/calorie?
The two subatomic particles that have a mass of approximately 1 amu.
What is the proton and the neutron?
Elements that are brittle and poor conductors of electricity.
What are nonmetals?
The type of bond created between Barium and Chlorine.
What is ionic?
When sand and water are mixed, it becomes this type of mixture.
What is heterogeneous?
When describing the flow of heat, it will always go in this "direction."
What is high to low?
The nuclear charge of potassium.
Elements in the same period of the periodic table have this property in common.
What is principal energy levels?
The maximum number of covalent bonds carbon can form.
What is four?
The name of the phase change illustrated in the formula below:
CO2(s) --> CO2(g)
What is sublimation?
Given two samples of water:
Sample 1: 100. grams of water at 10.oC
Sample 2: 100. grams of water at 20.oC
This sample has a higher average kinetic energy.
What is Sample 2?
2-7-7 the electron configuration of sulfur in this state.
What is the excited state?
The element with the greatest attraction for other atom's electrons.
This property of ionic bonds distinguishes them from metallic when testing electrical conductivity.
What is poor conductivity in the solid state/electrolyte?
The term used to express a homogenous solution of a solute mixed with water.
The type of energy transferred when an ice cube at 0oC is placed in a beaker of water at 50oC.
What is thermal energy?
Isotopes of any given atom affect this measurement provided on the periodic table.
What is the atomic mass.
This periodic table trend increases as you go down a group but decreases as you go left to right across a period.
What is atomic radius?
This symmetrical molecule contains three atoms that have polar covalent bonds.
What is carbon dioxide, CO2? (Any related compounds are accepted).
The separation technique that would be used to separate ink into its colors.
What is chromatography?
The amount of heat absorbed when 100 grams of water are heated from 20.0oC to 50.0oC.
What is 12,540 joules of heat?
This experiment concluded that atoms are mostly empty space with a dense positively charged nucleus.
What is the gold foil experiment?
An element that has a greater electronegativity than aluminum, greater metallic character than fluorine, lower ionization energy than nitrogen, and a smaller radius than arsenic that is located in group 15.
What is phosphorous?
The shape of a compound that has an uneven distribution of electrons between three atoms.
What is Bent?
