Atomic Structure
A single atom is made of these three types of particles.
What are protons, neutrons, and electrons?
What are noble gases?
This property of a gas describes the amount of collisions the particles of a gas make with the container.
What is pressure?
This type of matter is composed of two or more elements in a fixed ratio and cannot be broken down by physical means.
What is a compound?
This metric prefix literally means "one thousand".
What is kilo?
This subatomic particle is so tiny, it does not contribute to the mass of an atom.
What is an electron?
This type of element is what most of the elements on the periodic table are, located on the left side of the table.
What are metals?
Boyle's Law relates these two properties which are inversely related.
What are pressure and volume?
This property of matter, which is a ratio of mass and volume, can sometimes be used to identify a sample.
What is density?
This unit of measurement is used to quantify an amount of energy.
What are Joules?
This type of subatomic particle has a positive charge, contributes to the mass of an atom, is located in the nucleus, and dictates the elemental identify of the atom.
What is a proton?
This periodic table group on the periodic table is made of very reactive nonmetals.
What are halogens?
This type of substance has particles that move in a straight line with random motion, have perfectly elastic collisions, and have negligible particle volume.
What is an ideal gas?
During this type of reaction, thermal energy is released.
What is exothermic?
This unit of measurement for temperature is always used in gas law calculations because it is a direct measure of particle motion.
What is Kelvin?
This type of subatomic particle has no charge, contributes to the mass of an atom, and is located in the nucleus.
What is a neutron?
The atomic number of an element describes this, in relation to the structure of a single atom of an element.
What is number of protons?
Two sealed containers, A and B, hold the same amount of gas at the same temperature. Container A has twice the volume of container B. Which container has a higher pressure?
What is container B?
This type of matter is an even mix of substances throughout, but they are not combined at the chemical level.
What is a homogeneous mixture?
This type of quantitative relationship describes variables that increase together or decrease together.
What is a direct relationship?
What are valence electrons?
This element makes up about 75% of all matter in the observable universe and in its most common form, does not have any neutrons.
What is hydrogen?
A gas sample starts at 2.0 L, 1.0 atm, and 300 K. It is compressed to 1.0 L and heated to 600 K. The final pressure is...
What is 4.0 atm?
This term describes the amount of thermal energy per unit of mass of a substance can hold before its temperature increases by 1 degree.
What is specific heat capacity?
This quantity represents a fixed number of particles, just like a “dozen,” but is used for atoms, molecules, or ions.
What is a mole?
