Periodic Table
These elements are the most stable on the periodic table.
What are the Noble Gases?
This scientist is credited for discovering the periodic table, but did not believe in atoms.
Who was Dmitiri Mendeleev?
This occurs when an element changes to a different element.
What is radioactivity?
When a solution's solutes are equally dispursed throughout a solution, it is said to be this.
What is a homogenous mixture?
This is a line that delineates whether a solution is saturated or diluted.
What is a solubility curve?
What part of the atom identifies it as a specific element?
Protons
This scientist had an affinity to arsenic and contributed much to elemental discoveries of the periodic table by discovering the color of elements when they burn.
Who was Robert Bunson?
This element has a gaseous state, is dissolvable in water, creates complex molecules, and is dominant in every living thing.
What is Carbon?
This is a method used to seperate solutions, which is famously used for rock candy.
What is recrystallization?
Conductivity increases as these increase in a solution.
What are cations and anions?
This part of an atom varies within the same element, but significantly changes the mass.
What are Neutrons?
Gilbert Lewis discovered that bases are donors of this subatomic particle.
What is an electron?
We can figure this out by multiplying the coeffient and subscript of the molecule.
What is the total number of atoms of an element in a molecule?
This describes the material in a solution that is the minor component.
What is a solvent?
This unit changes the atomic mass into something measureable in a lab.
What is molar mass?
When an atom looses or gains an electron, it becomes charged and is called something.
What is an ion?
Maria Goeppert-Mayer was a scientist who discovered that electrons are layed out around the nucleus in these.
What are shells?
When balancing an equation, we cannot change the subscripts of the molecules, but we can change this.
What is a Coefficient?
This type of mixture seperation uses an analyte, mobile phase, and a stationary phase.
What is chromatography?
This number is an atomic mass multiplied by 6.022 x 1023
What is Avogadro's number?
This column on the periodic table, due to their unstable nature, often bond with the Hologen elements found on the periodic table.
What are the Alkali Metals?
Bardeen and Brattain were scientists who built the first transistor out of this element.
What is germanium?
This is the element, which looks much like Aluminum, that the book The Disappearing Spoon refers to.
What is Gallium?
This value determines the solubility of a solute from 0 to 1. 1 being most soluble, to 0 not soluble at all.
What is the retardation factor, or Rf factor?
This type of reaction occurs when a molecule is broken down into multiple molecules.
What is a decomposition reaction?
