Phases of Matter
A substance that has mass and takes up space by having volume.
What is Matter?
Outermost shell of an atome.
What is a valence shell?
The difference you get when you subtract the number of protons from the atomic mass.
What is the number of neutrons?
The center of an atom consisting of neutrons and protons.
What is a nucleus?
Pressure, Volume, Temperature, and the amount of gas
What variables affect the behavior of gas?
The most energy in a state of matter
What is Gas?
The chemical rule of thumb for most elements to have eight electrons in its outermost shell.
What is the Octet Rule?
Soft or brittle elements that have poor mechanical strength also known as poor metals.
What are Post-Transition Metals?
Has 10 electrons, 2 in the inner energy level and 8 in the outer energy level that release absorbed energy in the form of photons or life particles.
What is a neon atom?
The pressure of a given amount of gas held at constant volume is directly proportional to the Kelvin temperature.
What is Guy Lussac's Law?
As a gas is heated, the pressure of the gas in the sphere increases.
What is a Positive Correlation?
Where the lowest energy electron is found closest to the nucleus.
What is an S-Orbital?
The increase of energy across a period and the decrease of energy down a group.
What is Ionization Energy?
Matter that is made of small, indivisible particles when joined together make different things by forming in different combinations.
What is Daltons Spherical Atomic Model?
The relationship between volume and temperature if the pressure and the amount of gas are held constant.
What is Charles´ Law?
Molecules with very weak bonds or no bonds at all that move freely and quickly, and expand and conform to fill the shape of its container.
What is a gas?
Electrons that fill lower energy atomic orbital before filling in higher energy ones also known as the building-up principle.
What is the Aufbau Principle?
The representation of the valence electrons of an atom within a molecule.
What is a Lewis Dot Structure?
The region in an atom that encloses where the electron is 90% of the time.
What is an atomic orbit?
The inverse relationship with the increase of gas pressure and the decrease of the volume of gas.
What is Boyle´s Law?
The amount of matter in a system is conserved.
What is the Law of Conservation of Matter?
[He] 2s2 2p2
What is the electron configuration of Carbon?
The measurement of distance between the atoms positively charged nucleus and the atoms negatively charged valence electrons.
What is Atomic Radius?
Also know as the chocolate chip model of an atom that are uniformly packed spheres of positive matter filled with negatively charged electrons.
What is Thompson's Atomic Model?
The combination of Boyle's Law, Charles' Law and Gay-Lussac's Law that states the ratio between between the product of pressure and volume, and absolute temperature of a gas is a constant.
What is the Combined Gas Law?
